Explaining muon g-2 data in the μνSSM

We analyze the anomalous magnetic moment of the muon g-2 in the mu nu SSM. This R-parity violating model solves the mu problem reproducing simultaneously neutrino data, only with the addition of right-handed neutrinos. In the framework of the mu nu SSM, 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 mu nu SSM 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 mu 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 mu nu SSM can explain muon g-2 data.
