Neutrinophilic nonstandard interactions

摘要: We construct UV-complete models for nonstandard neutrino interactions mediated by a sub-GeV gauge boson ${Z}^{\ensuremath{'}}$ coupled to baryon number $B$ or $B\ensuremath{-}L$. A flavor-dependent coupling neutrinos is induced mixing $U(1{)}^{\ensuremath{'}}$-charged Dirac fermion with the active neutrinos, naturally suppressing flavor violation nonuniversality of charged leptons loop level. show that these can give rise large flavor-conserving as well flavor-violating neutral-current potentially observable in current future oscillation experiments such DUNE without being conflict other constraints scattering lepton-flavor-violating decays. In particular, LMA-Dark solution solar-neutrino anomaly be obtained $U(1{)}_{B}$, but not $U(1{)}_{B\ensuremath{-}L}$.
