Abstract
A lower bound of 5.4× is shown to follow on the gravitino-photino mass ratio from the observed lack of occurrence of the processes , , where and are the nearly massless chiral scalar and pseudoscalar, respectively. For a large class of theories with unified gaugino masses, this is convertible into a lower limit of 6.5× GeV on the gravitino mass.
