Description
The first results on next-to-leading order QCD corrections to production of direct photon pairs in hadronic collisions in the extra dimension models - ADD and RS are presented. Various kinematical distributions are obtained to order αs in QCD by taking into account all the parton level subprocesses. Our Monte Carlo based code incorporates all the experimental cuts suitable for physics studies at the LHC. We estimate the impact of the QCD corrections on various observables and find that they are significant. We also show the reduction in factorization scale uncertainty when O(αs) effects are included.
