Probing large distance higher dimensional gravity from lensing data

Abstract

The modifications induced in the standard weak-lensing formula if Newtonian gravity differs from inverse square law at large distances are studied. The possibility of putting bounds on the mass of gravitons from lensing data is explored. A bound on graviton mass, esitmated to be about 100 Mpc${}^{-1}$ is obtained from analysis of some recent data on gravitational lensing.
