Phys. Rev. D 62, 053001 (2000) [5 pages]Slepton flavor mixing and neutrino massesReceived 2 December 1999; published 18 July 2000 It is pointed out that important contributions to neutrino masses and mixing can come from flavor violating slepton exchange. For low and intermediate tanβ such effects can dominate over the usual tau Yukawa coupling effects included in renormalization group evolution. The mixing angles satisfy then a relation different from the fixed point solution of the renormalization group equation, and the desired neutrino mass splitting can be generated. © 2000 The American Physical Society URL:
