Descripción
We analyze the anomalous magnetic moment of the muon g- 2 in the μνSSM. This R-parity violating model solves the μ problem reproducing simultaneously neutrino data, only with the addition of right-handed neutrinos. In the framework of the μνSSM, light left muon-sneutrino and wino masses can be naturally obtained driven by neutrino physics. This produces an increase of the dominant chargino-sneutrino loop contribution to muon g- 2 , solving the gap between the theoretical computation and the experimental data. To analyze the parameter space, we sample the μνSSM using a likelihood data-driven method, paying special attention to reproduce the current experimental data on neutrino and Higgs physics, as well as flavor observables such as B and μ decays. We then apply the constraints from LHC searches for events with multi-leptons + MET on the viable regions found. They can probe these regions through chargino–chargino, chargino–neutralino and neutralino–neutralino pair production. We conclude that significant regions of the parameter space of the μνSSM can explain muon g- 2 data.
