Abstract: (arXiv)
We study the impact of initial-state multiple parton radiation on transverse momentum distribution of Higgs boson produced via bottom quark fusion at hadron colliders. The shape of the resulting 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 . 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- kinematics of Higgs boson. The results of this resummation are compared to fixed-order and PYTHIA predictions.- Higgs physics
