Description
Gravitino has been shown as another viable candidate for dark matter from
supergravity models. Gravitino interacting very weakly with other particles, being
suppressed by the Planck mass, and as a consequence the Next Lightest Supersymmetric
Particle (NLSP) could have a very long lifetime, i.e. becomes a metastable particle.
Also because of this very weak interaction , gravitino would be very difficult to
detect. The phenomenology of this scenario would depend on the signatures from the
NLSP. In this talk I would like to discuss about the feasibility and phenomenology of
the stop as the NLSP in a scenario with gravitino LSP as the dark matter.
