http://itunescontent.ucdavis.edu/media/0809/ucdpps/surya.mp4
In the causal set approach to quantum gravity the spacetime continuum arises as an approximation to a fundamentally discrete substructure, the causal set, which is a locally finite partially ordered set. The causal set paradigm was elucidated in a classic paper by Bombelli, Lee, Meyer and Sorkin in 1987. While early kinematical results already showed promise, the program received a substantial impetus about a decade ago with the work of Rideout and Sorkin on a classical stochastic growth dynamics for causal sets. Considerable progress has been made ever since in our understanding of causal set theory while leaving undisturbed the basic paradigm. Recent highlights include a causal set expression for the Einstein-Hilbert action and the construction of a scalar field Feynman propagator on a fixed causal set.5009Tue, 17 May 2011 07:00:00 GMThttp://itunescontent.ucdavis.edu/media/0809/ucdpps/surya.mp4131Sumati Suryahigh, energy, particle, physics, gravityConstructing a Dynamics for Causal SetsIn the causal set approach to quantum gravity the spacetime continuum arises as an approximation to a fundamentally discrete substructure, the causal set, which is a locally finite partially ordered set.

http://itunescontent.ucdavis.edu/media/0809/ucdpps/gherghetta.mp4
An emergent or accidental supersymmetry is used to address the little hierarchy problem in Randall-Sundrum models by naturally generating a hierarchy between the IR scale and the electroweak scale. Supersymmetry is broken on the UV brane which triggers the stabilization of the warped extra dimension at an IR scale of order 10 TeV. This causes the first two sparticle generations to decouple, thereby avoiding the supersymmetric flavour and CP problems, while an accidental R-symmetry protects the gaugino mass. The resulting low-energy sparticle spectrum consists of stops, gauginos and Higgsinos which are sufficient to stabilize the little hierarchy between the IR scale and the electroweak scale. Introducing a singlet Higgs field on the IR brane, ameliorates the supersymmetric little hierarchy problem, and allows Higgs masses up to 300 GeV.4699Mon, 23 May 2011 07:00:00 GMThttp://itunescontent.ucdavis.edu/media/0809/ucdpps/gherghetta.mp4133Tony Gherghettahigh, energy, particle, physics, susyGenerating a little hierarchy with accidental SUSYAn emergent or accidental supersymmetry is used to address the little hierarchy problem in Randall-Sundrum models by naturally generating a hierarchy between the IR scale and the electroweak scale.

Jiji Fan discusses a broad class of supersymmetric models that preserve R-parity but lack missing energy signatures. These models have new light particles with weak-scale supersymmetric masses that feel SUSY breaking only through couplings to the MSSM. This small SUSY breaking leads to nearly degenerate fermion/boson pairs, with small mass splittings and hence small phase space for decays carrying away invisible energy. The simplest scenario has low-scale SUSY breaking, with missing energy only from soft gravitinos.3309Tue, 20 Sep 2011 07:00:00 GMThttp://itunescontent.ucdavis.edu/media/0809/ucdpps/fan.mp4134Jiji Fansupersymmetry, high, energy, particle, physics, LHC UC Davis Jiji FanStealth SupersymmetryJiji Fan discusses a broad class of supersymmetric models that preserve R-parity but lack missing energy signatures.

http://itunescontent.ucdavis.edu/media/0809/ucdpps/bai.mp4
Yang Bai argues that dark matter particles that have strong interactions with the Standard Model particles are not excluded by current astrophysical constraints. These dark matter particles have unique signatures at colliders; instead of missing energy, the dark matter particles produce jets. We propose a new search strategy for such strongly interacting particles by looking for a signal of two trackless jets. We show that suitable cuts can plausibly allow us to find these signals at the LHC even in early data.4666Tue, 04 Oct 2011 07:00:00 GMThttp://itunescontent.ucdavis.edu/media/0809/ucdpps/bai.mp4137Yang Baihigh, energy, particle, physics, LHC, dark, matterNon-standard Dark Matter Signatures at the LHCYang Bai argues that dark matter particles that have strong interactions with the Standard Model particles are not excluded by current astrophysical constraints.

Jason Evans discuss the implications of the excesses in LHC Higgs boson searches on the gauge mediated supersymmetric standard model, for the mass range 120-140 GeV. A relatively heavy lightest Higgs boson mass in this range can be reconciled with light SUSY particles, if there are additional fields which couple directly to the Higgs boson. The mass of this extra matter can be predicted rather precisely in gauge mediation for a given Higgs boson and gluino mass.3920Mon, 10 Oct 2011 07:00:00 GMThttp://itunescontent.ucdavis.edu/media/0809/ucdpps/evans-oct-11.mp4138Jason Evanshigh, energy, particle, physics, LHC, supersymmetryRelatively Heavy Higgs Boson in More Generic Gauge MediationJason Evans discuss the implications of the excesses in LHC Higgs boson searches on the gauge mediated supersymmetric standard model, for the mass range 120-140 GeV.

Jared Kaplan discusses how to derive a simple relation between the Mellin amplitude for AdS/CFT correlation functions and the bulk S-Matrix in the flat spacetime limit, proving a conjecture of Penedones. As a consequence of the Operator Product Expansion, the Mellin amplitude for any unitary CFT must be a meromorphic function with simple poles on the real axis. This provides a powerful and suggestive handle on the locality vis-a-vis analyticity properties of the S-Matrix. We begin to explore analyticity by showing how the familiar poles and branch cuts of scattering amplitudes arise from the holographic description. We use this to show how the existence of small black holes in AdS leads to a universal prediction for the conformal block decomposition of the dual CFT.4025Mon, 30 Jan 2012 08:00:00 GMThttp://itunescontent.ucdavis.edu/media/0809/ucdpps/kaplan_d.mp4158Jared Kaplanhigh, energy, particle, physics, AdS CFTThe Holographic S-MatrixJared Kaplan discusses how to derive a simple relation between the Mellin amplitude for AdS/CFT correlation functions and the bulk S-Matrix in the flat spacetime limit, proving a conjecture of Penedones.

http://itunescontent.ucdavis.edu/media/0809/ucdpps/shirman.mp4
Yuri Shirman describes a simple recipe for obtaining local supersymmetry-breaking vacua in s-confining theories coupled to gauge singlets. This recipe gives rise to effective O'Raifeartaigh models in the IR, with calculable supersymmetry-breaking minima near the origin and can be applied to both vector-like and chiral theories. Since the properties of the vacuum are largely determined by superpotential terms that are non-renormalizable in the UV, it is calculable even when all dimensionless couplings are taken to be of order one. By construction, the models preserve a large subgroup of the original global symmetry. While we only study here s-confining theories, we expect our tools to be useful for inducing dynamical supersymmetry breaking in many gauge theories.3909Mon, 05 Mar 2012 08:00:00 GMThttp://itunescontent.ucdavis.edu/media/0809/ucdpps/shirman.mp4167Yuri Shirmanhigh, energy, particle, physics, LHC, supersymmetrySinglet assisted supersymmetry breakingYuri Shirman describes a simple recipe for obtaining local supersymmetry-breaking vacua in s-confining theories coupled to gauge singlets.

Sergey Dubovsky discusses the effective field theory of long relativistic strings such as confining flux tubes in QCD. We derive the Polchinski-Strominger interaction by a calculation in static gauge. This interaction implies that a non-critical string which initially oscillates in one direction gets excited in orthogonal directions as well. In static gauge no additional term in the effective action is needed to obtain this effect. It results from a one-loop calculation using the Nambu-Goto action. Non-linearly realized Lorentz symmetry is manifest at all stages in dimensional regularization. We also explain that independent of the number of dimensions non-covariant counterterms have to be added to the action in the commonly used zeta-function regularization.5838Tue, 13 Mar 2012 07:00:00 GMThttp://itunescontent.ucdavis.edu/media/0809/ucdpps/dubovsky-mar-12.mp4168Sergey Dubovskyhigh, energy, particle, physics, string, QCDSolving the Simplest Theory of Quantum GravitySergey Dubovsky discusses the effective field theory of long relativistic strings such as confining flux tubes in QCD.

http://itunescontent.ucdavis.edu/media/0809/ucdpps/barnard.mp4
It is widely believed that the emergent magnetic gauge symmetry of SQCD is analogous to a hidden local symmetry (HLS). James Barnard explores this idea in detail, deriving the entire (spontaneously broken) magnetic theory by applying the HLS formalism to spontaneously broken SU(N) SQCD. We deduce the Kahler potential in the HLS description, and show that gauge and flavour symmetry are smoothly restored along certain scaling directions in moduli space. We propose that it is these symmetry restoring directions, associated with the R-symmetry of the theory, that allow full Seiberg duality. Reconsidering the origin of the magnetic gauge bosons as the rho-mesons of the electric theory, colour-flavour locking allows a simple determination of the parameter "a". Its value continuously interpolates between a=2 on the baryonic branch of moduli space - corresponding to "vector meson dominance" - and a=1 on the mesonic branch. 3837Mon, 07 May 2012 07:00:00 GMThttp://itunescontent.ucdavis.edu/media/0809/ucdpps/barnard.mp4182James Barnardhigh, energy, particle, physics, supersymmetrySeiberg duality versus hidden local symmetryIt is widely believed that the emergent magnetic gauge symmetry of SQCD is analogous to a hidden local symmetry (HLS).

http://itunescontent.ucdavis.edu/media/0809/ucdpps/toshifumi.mp4
The bulk matter Randall-Sundrum (RS) model is a setup where Standard Model (SM) matter and gauge fields reside in the bulk of 5D warped spacetime while the Higgs field is confined on the IR brane. The wavefunctions of the 1st and 2nd generation matter particles are localized towards the UV brane and those of the 3rd generation towards the IR brane, so that the hierarchical structure of the Yukawa couplings arises geometrically without hierarchy in fundamental parameters. This paper discusses an experimental test of this model in the case where the Kaluza-Klein scale is far above the collider scale, but the model is combined with 5D Minimal SUSY Standard Model (MSSM) and SUSY particles are in the reach of collider experiments. A general SUSY breaking mass spectrum consistent with the bulk matter RS model is considered: SUSY breaking sector locates on the IR brane and its effects are mediated to 5D MSSM through a hybrid of gravity mediation, gaugino mediation and gauge mediation. 4298Mon, 21 May 2012 07:00:00 GMThttp://itunescontent.ucdavis.edu/media/0809/ucdpps/toshifumi.mp4185Yamada Toshifumihigh, energy, particle, physics, LHCObserving signals of the bulk matter RS model The bulk matter Randall-Sundrum (RS) model is a setup where Standard Model (SM) matter and gauge fields reside in the bulk of 5D warped spacetime while the Higgs field is confined on the IR brane.

The W boson mass is a crucial parameter in the standard model of particle physics, providing constraints on the mass of the Higgs boson as well as on new physics models via quantum loop corrections. Bo Jayatilaka describes the measurement of the W boson mass using data corresponding to 2.2/fb of integrated luminosity collected with the CDF II detector. The measurement, performed using electron and muon decays of W bosons, yields a mass of 80387±19 MeV. This represents the single most precise measurement of the W boson mass ever performed, significantly surpassing the precision of all prior measurements combined. An updated world average of the W boson mass, including all recent Tevatron measurements, as well as the resulting standard model implications, is presented.3175Mon, 04 Jun 2012 07:00:00 GMThttp://itunescontent.ucdavis.edu/media/0809/ucdpps/jayatilaka.mp4187Bo Jayatilakahigh, energy, particle, physics, CDFPrecision measurement of the W boson mass at CDFThe W boson mass is a crucial parameter in the standard model of particle physics, providing constraints on the mass of the Higgs boson as well as on new physics models via quantum loop corrections.

http://itunescontent.ucdavis.edu/media/0809/ucdpps/zhao.mp4
Recent signs of a Standard Model-like Higgs at 125 GeV point towards large A-terms in the MSSM. This presents special challenges for gauge mediation, which by itself predicts vanishing A-terms at the messenger scale. In this paper, we review the general problems that arise when extending gauge mediation to achieve large A-terms, and the mechanisms that exist to overcome them. Using these mechanisms, we construct weakly-coupled models of low-scale gauge mediation with extended
Higgs-messenger couplings that generate large A-terms at the messenger scale and viable mu/Bmu-terms. Our models are simple, economical, and complete realizations of supersymmetry at the weak scale.4085Mon, 01 Oct 2012 07:00:00 GMThttp://itunescontent.ucdavis.edu/media/0809/ucdpps/zhao.mp4188Yue Zhaohigh, energy, particle, physics, LHC, supersymmetryA Complete Model of Low-Scale Gauge MediationRecent signs of a Standard Model-like Higgs at 125 GeV point towards large A-terms in the MSSM.

Jason Gallicchio explains how distinguishing light-quark jets from gluon jets on an event-by-event basis could significantly enhance the reach for many new physics searches at the Large Hadron Collider. Through an exhaustive search of existing and novel jet substructure observables, we find that a combination of two simple variables, the charge track multiplicity and the p_T-weighted linear radial moment (width), can filter out over 85-95% of the gluon jets while keeping more than half of the light-quark jets. I will discuss applications, address theoretical issues in the definitions of quark and gluon jets, and show progress that ATLAS has made in measuring these observables.3870Tue, 02 Oct 2012 07:00:00 GMThttp://itunescontent.ucdavis.edu/media/0809/ucdpps/gallicchio-oct-12.mp4189Jason Gallicchiohigh, energy, particle, physics, LHC, QCDQuark/Gluon Tagger in Theory and DataJason Gallicchio explains how distinguishing light-quark jets from gluon jets on an event-by-event basis could significantly enhance the reach for many new physics searches at the Large Hadron Collider.

http://itunescontent.ucdavis.edu/media/0809/ucdpps/tsai_oct_2012.mp4
Weak scale SUSY with R-symmetry is a plausible solution to the SUSY flavor problem. In this talk, Yuhsin Tsai discusses two interesting aspects of R-symmetric SUSY models: electroweak baryogenesis and superpartner oscillations. Regarding baryogenesis, the new superpotential couplings between the adjoints and the Higgs can increase the strength of the electroweak phase transition, and large CP-violating phases consistent with electric dipole moments can generate large baryon asymmetry. R-symmetric models can also give spectacular signals at the LHC. If a tiny Majorana mass splits the degenerate mass eigenstates of gauginos and higgsinos, states produced at the LHC can oscillate between the spraticles and their Dirac mass partners. With displaced decays, the oscillation can be visible in the distribution of displaced vertex lengths at the LHC.3702Mon, 15 Oct 2012 07:00:00 GMThttp://itunescontent.ucdavis.edu/media/0809/ucdpps/tsai_oct_2012.mp4190Yuhsin Tsaihigh, energy, particle, physics, LHC, supersymmetryBaryogenesis and Superparter Oscillations in R-symmetric SUSYWeak scale SUSY with R-symmetry is a plausible solution to the SUSY flavor problem.

http://itunescontent.ucdavis.edu/media/0809/ucdpps/roy-oct-12.mp4
Jet substructure is typically studied using clustering algorithms, such as kT, which arrange the jets' constituents into trees. Instead of considering a single tree per jet, Tuhin Roy proposes that multiple trees should be considered, weighted by an appropriate metric. Then each jet in each event produces a distribution for an observable, rather than a single value. Advantages of this approach include: 1) observables have significantly increased statistical stability; and, 2) new observables, such as the variance of the distribution, provide new handles for signal and background discrimination. For example, we find that employing a set of trees substantially reduces the observed fluctuations in the pruned mass distribution, enhancing the likelihood of new particle discovery for a given integrated luminosity. Furthermore, we introduce a new quantity 'volatility', a cut on which reduces the luminosity needed for a given significance requirement by a factor of two.
