The pMSSM Interpretation of LHC Results Using Rernormalization Group Invariants
/ Carena, Marcela (Fermilab ; Chicago U., EFI ; Chicago U., KICP ; CERN) ; Lykken, Joseph (Fermilab) ; Sekmen, Sezen (CERN) ; Shah, Nausheen R. (Fermilab) ; Wagner, Carlos E.M. (Chicago U., EFI ; Chicago U., KICP ; Argonne)
The LHC has started to constrain supersymmetry-breaking parameters by setting bounds on possible colored particles at the weak scale. Moreover, constraints from Higgs physics, flavor physics, the anomalous magnetic moment of the muon, as well as from searches at LEP and the Tevatron have set additional bounds on these parameters.

MFV Reductions of MSSM Parameter Space
/ AbdusSalam, S.S. (INFN, Rome ; ICTP, Trieste) ; Burgess, C.P. (CERN ; McMaster U. ; Perimeter Inst. Theor. Phys.) ; Quevedo, F. (Cambridge U., DAMTP ; ICTP, Trieste)
The 100+ free parameters of the minimal supersymmetric standard model (MSSM) make it computationally difficult to compare systematically with data, motivating the study of specific parameter reductions such as the cMSSM and pMSSM. Here we instead study the reductions of parameter space implied by using minimal flavour violation (MFV) to organise the R-parity conserving MSSM, with a view towards systematically building in constraints on flavour-violating physics. [...]

General Focus Point in the MSSM
/ Delgado, Antonio (Notre Dame U.) ; Quiros, Mariano (CERN ; ICREA, Barcelona ; Barcelona, IFAE) ; Wagner, Carlos (Chicago U., EFI ; Argonne ; Chicago U., KICP)
The minimal supersymmetric extension of the Standard Model (SM) is a well motivated scenario for physics beyond the SM, which allows a perturbative description of the theory up to scales of the order of the Grand Unification scale, where gauge couplings unify. The Higgs mass parameter is insensitive to the ultraviolet physics and is only sensitive to the scale of soft supersymmetry breaking parameters. [...]

Direct Detection of Dark Matter in the MSSM with Non-Universal Higgs Masses
/ Ellis, John R. (CERN) ; Ferstl, Andy (Winona State U.) ; Olive, Keith A. (Minnesota U., Theor. Phys. Inst.) ; Santoso, Yudi (Minnesota U., Theor. Phys. Inst.)
We calculate dark matter scattering rates in the minimal supersymmetric extension of the Standard Model (MSSM), allowing the soft supersymmetry-breaking masses of the Higgs multiplets, m_{1,2}, to be non-universal (NUHM). Compared with the constrained MSSM (CMSSM) in which m_{1,2} are required to be equal to the soft supersymmetry-breaking masses m_0 of the squark and slepton masses, we find that the elastic scattering cross sections may be up to two orders of magnitude larger than values in the CMSSM for similar LSP masses.

Frequentist Analysis of the Parameter Space of Minimal Supergravity

(Durham U., IPPP) ; Ellis, J.R. (CERN ; King's Coll. London) ; Flacher, H. (Rochester U.) ; Heinemeyer, S. (Cantabria Inst. of Phys.) ; Olive, K.A. (Minnesota U., Theor. Phys. Inst.) ; Rogerson, S. (Imperial Coll., London) et al.
We make a frequentist analysis of the parameter space of minimal supergravity (mSUGRA), in which, as well as the gaugino and scalar soft supersymmetry-breaking parameters being universal, there is a specific relation between the trilinear, bilinear and scalar supersymmetry-breaking parameters, A_0 = B_0 + m_0, and the gravitino mass is fixed by m_{3/2} = m_0. We also consider a more general model, in which the gravitino mass constraint is relaxed (the VCMSSM). [...]

Exploring CP Violation in the MSSM
/ Arbey, A. (Lyon U. ; Lyon Observ. ; Lyon, Ecole Normale Superieure ; CERN) ; Ellis, J. (King's Coll. London ; CERN) ; Godbole, R.M. (Bangalore, Indian Inst. Sci.) ; Mahmoudi, F. (Lyon U. ; Lyon Observ. ; Lyon, Ecole Normale Superieure ; CERN)
We explore the prospects for observing CP violation in the minimal supersymmetric extension of the Standard Model (MSSM) with six CP-violating parameters, three gaugino mass phases and three phases in trilinear soft supersymmetry-breaking parameters, using the CPsuperH code combined with a geometric approach to maximize CP-violating observables subject to the experimental upper bounds on electric dipole moments. We also implement CP-conserving constraints from Higgs physics, flavour physics and the upper limits on the cosmological dark matter density and spin-independent scattering. [...]

CP Violation in Heavy MSSM Higgs Scenarios
/ Carena, M. (Chicago U., EFI ; Chicago U., KICP ; Fermilab) ; Ellis, J. (CERN ; King's Coll. London) ; Lee, J.S. (Chonnam Natl. U.) ; Pilaftsis, A. (CERN ; Manchester U.) ; Wagner, C.E.M. (Argonne ; Chicago U., EFI ; Chicago U., KICP)
We introduce and explore new heavy Higgs scenarios in the Minimal Supersymmetric Standard Model (MSSM) with explicit CP violation, which have important phenomenological implications that may be testable at the LHC. For soft supersymmetry-breaking scales M_S above a few TeV and a charged Higgs boson mass M_H+ above a few hundred GeV, new physics effects including those from explicit CP violation decouple from the light Higgs boson sector.

The Soft Supersymmetry-Breaking Lagrangian: Theory and Applications
/ Chung, D.J.H. (CERN ; Wisconsin U., Madison) ; Everett, L.L. (Florida U. ; CERN) ; Kane, G.L. (Michigan U., MCTP) ; King, S.F. (Southampton U.) ; Lykken, Joseph D. (Fermilab) ; Wang, Lian-Tao (Wisconsin U., Madison)
After an introduction recalling the theoretical motivation for low energy (100 GeV to TeV scale) supersymmetry, this review describes the theory and experimental implications of the soft supersymmetry-breaking Lagrangian of the general minimal supersymmetric standard model (MSSM). Extensions to include neutrino masses and nonminimal theories are also discussed. [...]

Beyond the CMSSM without an Accelerator: Proton Decay and Direct Dark Matter Detection
/ Ellis, John (King's Coll. London ; CERN) ; Evans, Jason L. (Minnesota U., Theor. Phys. Inst.) ; Luo, Feng (CERN) ; Nagata, Natsumi (Minnesota U., Theor. Phys. Inst. ; Tokyo U., IPMU) ; Olive, Keith A. (Minnesota U., Theor. Phys. Inst.) ; Sandick, Pearl (Utah U.)
We consider two potential non-accelerator signatures of generalizations of the well-studied constrained minimal supersymmetric standard model (CMSSM). In one generalization, the universality constraints on soft supersymmetry-breaking parameters are applied at some input scale $M_{in}$ below the grand unification (GUT) scale $M_{GUT}$, a scenario referred to as `sub-GUT'.
