The Photino Induced Distortion of the CMBR Blackbody Spectrum
Medvedev, M. V.
Original · EN
It is shown that photon--photino inter-conversions (if exist) may result in a detectable CMBR spectrum distortion which amplitude depends on photino properties, such as its mass. An upper bound on the distortion parameter determined from the recent COBE-FIRAS data, hence, sets a lower bound on the photino mass, mγ 300 eV.
