Fitting direct interaction pieces into neutrino puzzles

Academic Article

Abstract

  • We develop a framework and unified, compact notation to include neutrino direct interaction effects with neutrino oscillations for a wide class of low-energy, effective four-Fermi interactions. Modest flavor-violating interaction strengths can make significant changes in the boundaries in ΔM2 ↔ sin22θ and in tan2θ13 ↔ tan2θ23 parameter space. We draw examples from the L - R symmetric and MSSM + Slashed R sign models and find the recently reported decay-at-rest μ ↔ e transition probability can be described without oscillations in L - R symmetric models. © 1998 Published by Elsevier Science B.V.
