摘要：

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-S, P, 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. © 1990 The American Physical Society.
