Factorization scheme dependence of the NLO inclusive jet cross section

Abstract

We study the factorization scheme dependence of the next-to-leading order inclusive one jet cross section d sigma/dE_T. The scheme is varied parametrically along the direction that transforms the MSbar scheme to the DIS scheme: we introduce a parameter lambda such that lambda = 0 is MSbar and lambda = 1 is DIS. The factorization scale mu is also varied. We observe a change of +/- 9% in the cross section for E_T = 50 GeV when mu and lambda are varied in the range -2 < lambda < 2, E_T/8 < mu < 2 E_T. This grows to +/- 32% for E_T = 400 GeV.
