Measuring invisible particle masses using a single short decay chain

• Hsin-Chia Cheng

Room: TH Theory Conference Room We discuss the possibility of mass measurements for a SUSY-like decay chain with only 2 visible particles. This was never attempted and thought to be impossible before.

New Vector Boson Near the Z-pole and the Puzzle in Precision Electroweak Data

• Radovan Dermisek

Room: TH Theory Conference Room We show that a Z' with suppressed couplings to the electron compared to the Z-boson, with couplings to the b-quark, and with a mass close to the mass of the Z-boson, provides an excellent fit to forward-backward asymmetry of the b-quark and R_b measured on the Z-pole and $\pm 2$ GeV off the Z-pole, and to A_e obtained from the measurement of left-right asymmetry for hadronic final states.

CDF dijet excess

• Kenneth Lane (Boston University)

Room: TH Theory Conference Room how to look for the CDF dijet excess at the LHC (IF it's from rho_T -> W pi_T).

Natural supersymmetry at the LHC

• Hyung Do Kim (Unknown)

Room: TH Theory Conference Room Motivated by natural electroweak symmetry breaking in supersymmetry, an effective model with light stop/higgsino and very light gravitino is considered. The implication of the LHC 1 fb^-1 data is also discussed.

Tree-level Gauge Mediation: Viable and Predictive Tree-level SUSY breaking

• Robert Ziegler (Technische Universitat Munchen)

Room: TH Theory Conference Room I will discuss a scenario in which SUSY breaking is communicated by heavy vectorfields at tree-level. This gives rise to a simple and motivated model of SUSY breaking with peculiar predictions for sfermion mass ratios.

Model building using Lie-point symmetries

• Damien George

Room: TH Theory Conference Room We describe the Lie-point symmetry method and how it can be used to systematically search for all continuous symmetries and parameter relationships in a classical field theory.

Physical Predictions in the Quantum Multiverse

• Yasunori Nomura

Room: TH Theory Conference Room I describe how quantum mechanics plays a crucial role in defining probabilities (the "measure") in the multiverse, and how the eternally inflating multiverse leads to dramatic change of our view on spacetime and gravity. The latest result on the distribution of the cosmological constant is also presented. The talk is based mainly on arXiv:1104.2324 (but also arXiv:1107.3556).

MSSM Higgs physics at the LHC

• Carlos Wagner (University of Chicago and Argonne National Laboratory)

Room: TH Theory Conference Room I'll discuss the reach of the 7 TeV LHC in the search for Standard Model-like Higgs bosons in different benchmark scenarios, as well as the complementarity of the standard searches with non-standard Higgs searches. Searches from SUSY Higgs bosons from cascade decays will also be discussed in some detail.

The fine-tuning and phenomenology of the generalised NMSSM

• Kai Schmidt-Hoberg (University of Oxford)

Room: TH Theory Conference Room We determine the degree of fine-tuning needed in a generalised version of the NMSSM that follows from an underlying Z4 or Z8 R-symmetry. We find that it is significantly less than is found in the MSSM or NMSSM and remarkably the minimal fine-tuning is achieved for Higgs masses of 130 GeV - 140 GeV.

Extended Higgs sector at the LHC Run-I

• José Francisco Zurita (University of Zurich)

Room: TH Theory Conference Room In this talk I will discuss the exclusion and detectability prospects of Higgs bosons in three models: a) the Lee Wick Standard Model (arXiv:1104.3496), b) Beyond Minimal Supersymmetric Standard model (BMSSM) and c) Higgs portal models. We discuss the collider bounds on this model coming from LEP, Tevatron and LHC data.

Two-Higgs-doublet interpretation of a small Wjj excess

• John Gunion (UC Davis)

Latest H->WW Results from ATLAS and CMS

• Dmytro Kovalskyi
• Elliot Lipeles

Room: 4/2-011 - TH common room Collider Cross Talk. Abs:The search for the Standard Model-like Higgs boson via the decay into two W bosons is presented, based on data collected in 2011. The search in the dilepton final state is more powerful than any current result for intermediate mass Higgs bosons and has the highest sensitivity of the Higgs searches at the LHC. It is complemented by semi-leptonic WW decays which give good performance in the region of high mass. Recent results by ATLAS and CMS will be discussed and the current limits on the Higgs mass will be shown.

Relating Proton Decay and Monojets through Asymmetric Dark Matter

• David Morrissey (Michigan State University)

Room: TH Theory Conference Room n this talk I will discuss a scenario for asymmetric dark matter where the stable ADM states carry a (generalized) baryon number and can destroy nucleons through inelastic scattering, the rate for which is closely related to the cross section for monojet signals at the Tevatron and the LHC.
