Abstract
SynopsisIf the gravitino mass is in the region from a few GeV to a few 10’s GeV, the scalar lepton X− such as stau is most likely the next lightest supersymmetry particle. The negatively charged and long-lived X− can form a Coulombic bound state, an exotic atom, with a nucleus. Energy levels and structures of exotic molecules consisting of two nuclei and X− are precisely calculated. We discuss stabilities of the exotic molecule and intramolecular nuclear reactions.
