Abstract
A lower bound of 5.4×10−16 is shown to follow on the gravitino-photino mass ratio from the observed lack of occurrence of the processes e+e−→γS, γP, where S and P 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 6.5×10−15 GeV on the gravitino mass.
