Constraining the MSSM with universal gaugino masses and implication for searches at the LHC

Understand

Using a Markov chain Monte Carlo approach, we find the allowed parameter space of a MSSM model with seven free parameters.

• In this model universality conditions at the GUT scale are imposed on the gaugino sector.
• We require in particular that the relic density of dark matter saturates the value extracted from cosmological measurements assuming a standard cosmological scenario.
• We characterize the parameter space of the model that satisfies experimental constraints and illustrate the complementarity of the LHC searches, B-physics observables and direct dark matter searches for further probing the parameter space of the model.
