Graviton production through photon-quark scattering at the LHC

Understand

We have investigated real graviton emission in the ADD and RS model of extra dimensions through the photoproduction process pp-> p gamma p-> pGqX at the LHC.

• We have considered all contributions from the subprocesses gamma q -> G q, where q=u,d,c,s,b,anti-u,anti-d, anti-c, anti-s, anti-b quark.
• The constraints on model parameters of the ADD and RS model of extra dimensions have been calculated.
• During numerical calculations we have taken account of 3, 4, 5 and 6 large extra dimensional scenarios.
