Description
I will discuss the potential of cosmic shear to constraint the light gravitino mass.
The gravitino mass, that is directly related to the supersymmetry breaking scale, is one of most fundamental parameters in the supersymmetric theory.
In the gauge mediation supersymmetric breaking (GMSB) models, the gravitino is generically the lightest supersymmetric particle (LSP) with mass in the order of eV to keV.
While the collider experiment such as Large Hadron Collider (LHC) gives the lower bound of the light gravitino mass, the cosmic shear measurement can put the upper bound.
Combining the future LHC runs at 14 TeV and the forthcoming Subaru Hyper Suprime-Cam (HSC)- and Large Synoptic Survey Telescope (LSST)-like survey, we can reach almost all light gravitino mass in GMSB.
