Neutrino Mixing in the BLMSSM

In recent years, a nonzero value for the neutrino mixing angle 013 has been successively measured by the international famous reactor oscillation experiments, which is greater than 5 standard deviations. Our study is in the framework of the MSSM, where baryon and lepton numbers are local gauged symmetries (BLMSSM). This model can generate three tiny neutrino masses at the tree level through TeV scale seesaw mechanism. In our paper, we analyze the neutrino masses and their corresponding mixing angles with a "top-down" method, assuming neutrino mass spectrum with normal ordering (NO) and inverted ordering (IO).
