Description
In this talk I will present our work on phenomenology of supergravity models with R-parity breaking, in which the gravitino is the lightest superparticle and a bino-like neutralino is the next-to-lightest superparticle. Based on Fermi-LAT constraints on gravitino decays we estimated a lower bound on the neutralino decay length of $c \tau_{\chi^0_1} \gtrsim 30\ \rm cm$. We performed a detailed study on the sensitivity of LHC experiments to R-parity breaking. We found that the LHC can probe a parameter range which is one to two orders of magnitude smaller than the present upper bound obtained from astrophysics and cosmology.
