Neutrino Mixing in the BLMSSM

Abstract

In recent years, a nonzero value for the neutrino mixing angle θ13 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).

The corrections from one loop and two-loop Barr-Zee type diagrams to muon MDM in BLMSSM

“…For the input parameters, we take into account the experimental constraints from the lightest neutral CP even Higgs m In our previous work, we fit the neutrino experiment data shown as eq. (4.1) in BLMSSM [43].…”

The one loop corrections to the neutrino masses in BLMSSM

“…In the BLMSSM, the tree level neutrino mass mixing matrix is obtained in our previous work [16]. The obtained one loop corrections include: 1. the virtual slepton-chargino corrections; 2. the virtual sneutrino-lepton neutralino corrections; 3. the virtual sneutrinoneutralino corrections; 4. the virtual Higgs-charged lepton corrections; 5. the exotic Higgsneutrino corrections.…”

“…In the BLMSSM, the tree level neutrino mass mixing matrix is obtained in our previous work [16]. Using the top-down method, we give the formulae for the neutrino masses and mixing angles.…”

“…In the BLMSSM, because of the introduced right-handed neutrino fields, the three light neutrinos obtain tiny masses at tree level through the see-saw mechanism, which is shown in our previous work [16]. Here, using the mass insertion approximation we consider one loop corrections to the neutrino mass mixing matrix.…”

The study of lepton EDM in CP violating BLMSSM

“…In our previous works, the neutron EDM and muon MDM are studied [18,39], so the constraints from them are also considered here. We give out the used parameters [39][40][41] m e = 0.51 × 10…”
