| Description/Abstract | For massive neutrinos that can decay by emission of a familon ( f ), a flavor-changing axion, the upper bound on the cosmic energy density of the decay products yields (1) an upper bound on the familon decay constant, and consequently (2) a lower bound on other f emission rates. By comparing the K..--> pi..f lower bound with experimental upper bound, we rule out neutrinos that decay by familon emission and have masses between 5 x 10/sup -5/ and 0.1 MeV. |
