Mass Spectrum and Higgs Profile in BLSSM

Understand

We investigate the predictions on the mass spectrum and Higgs boson decays in the supersymmetric standard model extended by U(1)_B-L symmetry (BLSSM).

• The model requires two singlet Higgs fields, which are responsible for the radiative breaking of U(1)_B-L symmetry.
• It predicts degenerate right-handed neutrino masses (1.7-2.2 TeV) as well as the right-handed sneutrinos of mass <~ 4 TeV.
• The presence of right-handed neutrinos and sneutrinos trigger the baryon and lepton number violation processes, until they decouple from the Standard model particles.
