abstract

We reanalyse the limits on the gravitino mass $m_{3/2}$ in superlight gravitino scenarios derived from arguments on energy-loss during gravitational collapse. We conclude that the mass range $10^{-6}eV\leq m_{3/2}\leq2.3\times10^{-5}eV$ is excluded by SN1987A data. In terms of the scale of supersymmetry breaking $\Lambda$, the range $70GeV\leq\Lambda \leq 300GeV$ is not allowed.

    A heuristic model claims neutrino- and boson-mediated forces would shift black hole photon spheres and shadows, with attractive forces enlarging and repulsive forces shrinking them.
