Abstract
In the extra dimension models of ADD and RS we study the dependence of the various parton distribution functions on observables of Drell-Yan processes 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 µF range 0.5Q < µF < 1.5Q. Further uncertainties arising from the error on the experimental data are estimated using the MRST parton distribution functions.
