On evaluation of nonfactorizable corrections to Higgs boson production via vector boson fusion
Abstract
We present the fully analytical result for the next-to-next-to-leading nonfactorizable QCD corrections to Higgs boson production via vector boson fusion computed to the leading power in the ratio of the jet transverse momentum to the partonic center-of-mass energy. Asymptotic expansions of the nonfactorizable corrections in various kinematical limits are obtained.
