at CERN ( 4-3-006 - TH Theory Conference Room )
 Description The TH-LPCC Summer Institute on LHC Physics This 5-week Institute is co-organized by CERN's Theory Group and by the LHC Physics Centre at CERN. Format: The first two weeks of the Institute will be focused on SM and QCD while the last three weeks will be devoted to BSM, with a special emphasis on model building during the first two, and on the status of the searches at the LHC in the last one. In particular, during this week the Institute will host the first meeting of the Workshop on "Implications of LHC results for TeV-scale physics". This is open for participation to those not registered at the Institute, at https://indico.cern.ch/conferenceDisplay.py?confId=141983 Registration: The attendance will be limited to around 40 people per week. There is no registration fee. Registration will be open until Jan. 31, 2011. Local Organization: Stefano Frixione, Gian Giudice, Christophe Grojean, Michelangelo Mangano, Gavin Salam, Peter Skands and Geraldine Servant. The meeting will be partly supported by the CERN-TH unit the LHC Physics Centre at CERN the Marie Curie Initial Training Network "UNILHC" PITN-GA-2009-23792, and the ERC Advanced Grant "MassTeV" 226371.

• 11:40 - 12:00 New Vector Boson Near the Z-pole and the Puzzle in Precision Electroweak Data 20'
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.

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.
 Speaker: Hyung Do Kim Material:
• 14:20 - 14:40 Tree-level Gauge Mediation: Viable and Predictive Tree-level SUSY breaking 20'

 Speaker: Robert Ziegler (Technische Universitat Munchen) Material:
• 14:40 - 15:00 Model building using Lie-point symmetries 20'
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.
 Speaker: Damien George Material:
• 15:00 - 15:20 Physical Predictions in the Quantum Multiverse 20'
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).

• 11:20 - 11:40 MSSM Higgs physics at the LHC 20'
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.

• 11:40 - 12:00 The fine-tuning and phenomenology of the generalised NMSSM 20'
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.
 Speaker: Kai Schmidt-Hoberg (University of Oxford) Material:
• 12:00 - 12:20 Extended Higgs sector at the LHC Run-I 20'
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.

I describe how a Wjj excess could arise in the 2HDM context, related signals and the theoretical issues that require that the excess be smaller than the CDF claim.

• 11:00 - 12:00 Latest H->WW Results from ATLAS and CMS 1h0'
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.

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.
