Gravitino Dark Matter and Light Gluino in an R-invariant Low Scale Gauge Mediation
Masahiro Ibe, Ryosuke Sato, Tsutomu T. Yanagida +1
We consider the simplest class of the R-invariant gauge mediation model with the gravitino mass in the one to ten keV range. We show that the entropy production from the supersymme…

LHC Reach of Low Scale Gauge Mediation with Perturbatively Stable Vacuum
Ryosuke Sato, Satoshi Shirai
Very light gravitino scenario m_{3/2} < 16 eV is very interesting, since there is no cosmological problem. However in such a scenario, stability of the vacuum is an important issue…
