Sumario:The analysis of the data collected by the major LHC experiments during the LHC Run I has put strong constraints on supersymmetric models. We study the parameter space of the constrained Minimal Supersymmetric Standard Model (cMSSM) in a global fit, taking into account the non- observation of supersymmetry at the LHC, Higgs mass and rate measurements, as well as several cosmological and low energy observables. Before the start of the LHC, global fits of the cMSSM showed a favourable goodness-of-fit and indicated a strong preference for the existence of light SUSY particles. This region now has largely been excluded by the LHC. We present the final results of our study of the status of the cMSSM after the LHC Run1, where for the first time we use pseudo experiments to determine the p-value of the model. We find that the cMSSM is softly getting near its exclusion at the 90% CL.
