Probe of the Randall-Sundrum-like model with the small curvature via light-by-light scattering at the LHC

The LHC possibilities to constrain the parameters of the Randall-Sundrum-like model with one warped extra dimension and small curvature through the diphoton production in the photon-induced process pp -> p gamma gamma p -> p'gamma gamma p' are investigated. The acceptance of the forward detectors 0.015 < xi < 0.15, where. is the fractional proton momentum loss of the incident protons, is considered. The sensitivity bounds on the five-dimensional gravity scale are obtained as a function of the LHC integrated luminosity.
