摘要
We study the impact of initial-state multiple parton radiation on transverse momentum (q(T)) distribution of Higgs boson produced via bottom quark fusion at hadron colliders. The shape of the resulting q(T) distribution is affected by the bottom-quark mass corrections and by the strong kinematical behavior of the bottom-quark parton density. We account for both features in the full range of q(T). To do this, we formulate the resummation calculation in a general-mass factorization (S-ACOT) scheme and introduce a correction in the resummed-term to account for the effect from large-q(T) kinematics of Higgs boson. The results of this resummation are compared to fixed-order and PYTHIA predictions.
