Description
We present an updated global analysis of the GUT-constrained models CMSSM and CNMSSM, taking into account the recent observation of a SM Higgs-like signal at the LHC. In both our analyses, we implement the CMS razor limit on supersymmetry, based on ~5/fb datasets, with an approximate but accurate likelihood map constructed through a simulation of the detector efficiency.
In the CNMSSM we consider three possible scenarios: i) H1 is SM-like with mass around 125 GeV, ii) H2 is SM-like, with a mass of ~125 GeV and H1 escaped detection, and iii) H1 and H2 are almost degenerate in mass.
We identify the 68% and 95% credible posterior probability regions in both models employing a Bayesian approach. We find that it is possible to accomodate the recent observation of the Higgs in both models, although a 125-GeV Higgs mass shows some tension with various constraints.
