Description
If R-Parity is broken, a Gravitino LSP can still act as Dark Matter
due to the Planck scale suppression of the decay width. Within this
framework, we study cosmic ray signatures of models with trilinear R-
Parity Violating couplings. The signals are compared with cosmic ray
measurements from PAMELA and Fermi/LAT. It is shown that leptonic
operators (LLE) can successfully reproduce the electron/positron
anomalies seen by PAMELA and Fermi. Moreover, the absence of any
deviation from expected background in the PAMELA anti-proton data is
shown to produce significant constraints on LQD and UDD couplings.
Finally, we discuss the importance of upcoming photon data on
resolving the source of these anomalies.
