Abstract

In the extra dimension models of ADD and RS we study the dependence of the various parton distribution functions on observable of Drell-Yan process to NLO in QCD at LHC and Tevatron energies. Uncertainties at LHC due to factorisation scales in going from leading to next-to-leading order in QCD for the various distributions get reduced by about 2.75 times for a μ_F range 0.5 ~Q < μ_F < 1.5 ~Q. Further uncertainties arising from the error on experimental data are estimated using the MRST parton distribution functions.
