The potential of pp -> p gamma gamma p -> pGp process in scenarios of the Arkani-Hamed, Dimopoulos, Dvali (ADD) and Randall-Sundrum (RS) model at the LHC is examined, and 95% C.L. bounds on the model parameters are obtained. It is found that the sensitivity of the model parameters can be improved in the present colliders by using this reaction.
