The MSSM at the end of LHC Phase 1 - status report


  • Enrico Maria SESSOLO


The discovery of the Higgs boson at 126 GeV seems to imply masses in the multi-TeV regime for the simplest constrained SUSY models. Such a heavy supersymmetric spectrum is somewhat at odds with the naturalness criterion. Moreover, in such a framework it is impossible to obtain the correct value of $(g-2)_\mu$. By construction, SUSY models with light sleptons and light third generation squarks do not present the same problem. In this context we analyze the status of a version of the MSSM with 9 free parameters at the end of LHC Phase 1 runs. We investigate the impact on the parameter space of different direct SUSY searches using a statistical approach. We also include various other constraints from b-physics, the anomalous magnetic moment of the muon, the relic density and direct and indirect detection of dark matter. All experimental results are implemented through the likelihood functions, including the limits from XENON100 and from two 8 TeV CMS searches (inclusive search of SUSY particles with $\alpha_T$ and electroweak production), for which the likelihood is constructed through simulation of the signal yields to be compared with observed events and backgrounds given by the experimental collaborations.
