A model for large non-standard interactions of neutrinos leading to the LMA-Dark solution

摘要: Abstract It is well-known that in addition to the standard LMA solution solar anomaly, there another called LMA-Dark which requires Non-Standard Interactions (NSI) with effective couplings as large Fermi coupling. Although this satisfies all bounds from various neutrino oscillation observations and even provides a better fit low energy spectrum, it not popular mainly because no model compatible existing has been so far constructed give rise solution. We introduce foundation for such NSI strength flavor structure required This based on new U ( 1 ) ′ gauge interaction boson of mass ∼ 10 MeV under quarks well second third generations leptons are charged. show observable effects can appear spectrum supernova high cosmic neutrinos.
