RS model with a small curvature and two-photon production at the LHC

Understand

The p_trans-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 M_5 in the TeV region.

• The discovery limits on M_5 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 M_5.
• The account of graviton widths is a crucial points of our calculations.
