RS model with a small curvature and two-photon production at the LHC
Abstract
The ptrans-distribution for the diphoton production at the LHC is calculated in the modified Randall-Sundrum model with a small curvature of the space-time kappa, and 5-dimensional Planck scale M5 in the TeV region. The discovery limits on M5 are obtained to be 9.4 TeV and 11.6 TeV for the integrated luminosities 30 fb(-1) and 100 fb(-1), respectively. These limits do not depend on kappa provided it is much smaller than M5. The account of graviton widths is a crucial points of our calculations.
