Interpreting LHC SUSY searches in the phenomenological MSSM
نویسندگان
چکیده
We interpret within the phenomenological MSSM (pMSSM) the results of SUSY searches published by the CMS collaboration based on the first∼1 fb of data taken during the 2011 LHC run at 7 TeV. The pMSSM is a 19-dimensional parametrization of the MSSM that captures most of its phenomenological features. It encompasses, and goes beyond, a broad range of more constrained SUSY models. Performing a global Bayesian analysis, we obtain posterior probability densities of parameters, masses and derived observables. In contrast to constraints derived for particular SUSY breaking schemes, such as the CMSSM, our results provide more generic conclusions on how the current data constrain the MSSM.

Lepton Flavor Violation, Neutralino Dark Matter and the Reach of the LHC
We revisit the phenomenology of the Constrained MSSM with right-handed neutrinos (CMSSMRN). A supersymmetric seesaw mechanism, generating neutrino masses and sizable lepton flavour violating (LFV) entries is assumed to be operative. In this scheme, we study the complementarity between the ‘observable ranges’ of various paths leading to the possible discovery of low energy SUSY: the reach of the...
متن کاملDiscovery Potential for SUGRA/SUSY at CMS
The expected SUSY discovery potential of the CMS experiment at LHC is described, both in the MSSM and in the more constrained framework of mSugra, with emphasis on inclusive searches, the MSSM Higgs sector, and one example of complete reconstruction of a SUSY decay chain. Presented at SUGRA20, Boston, USA, 17-21 March, 2003.
متن کاملHiggs and SUSY Searches at LHC: An Overview
I start with a brief summary of Higgs mechanism and supersymmetry. Then I discuss the theoretical constraints, current limits and search strategies for Higgs boson(s) at LHC — first in the SM and then in the MSSM. Finally I discuss the analogous constraints and search strategies for the superparticles, concentrating on the minimal supergravity model. Recent advances in identifying the most prom...
متن کاملSusy and Dark Matter Constraints from the Lhc
The ability of the LHC to make statements about the dark matter problem is considered, with a specific focus on supersymmetry. After reviewing the current strategies for supersymmetry searches at the LHC (in both CMS and ATLAS), some key ATLAS studies are used to demonstrate how one could establish that SUSY exists before going on to measure the relic density of a neutralino WIMP candidate. Fin...
متن کاملExperimental Results on Searches beyond the Standard Model
We know from the corrections to the Higgs mass that new physics could be at a scale of 1 or few TeV. It would be possible then to see effects beyond the Standard Model (SM) at present colliders, and of course in future at the LHC. In this report, recent results from direct searches at HERA (up to 350 pb of integrated luminosity) and Tevatron (up to 1.2 fb) are reviewed. A review of the present ...
