Small-$p_T$ and large-$x$ regions for Higgs transverse momentum distributions
Abstract
It was shown recently that standard resummation of logarithms of can be supplemented with the resummation of logarithmic contributions at large in the case of a colourless final state such as Higgs produced via gluon fusion or the production of a lepton pair via Drell--Yan mechanism. Such an improved transverse momentum resummation takes into account soft emissions that are emitted at very small angles. We report on recent phenomenological studies of a combined threshold-improved and threshold resummation formalism to the Higgs boson produced at the LHC where small- and threshold logarithms are resummed up to NNLL and NNLL* respectively. We show that the effect of the modified resummation yields a faster perturbative convergence in the small- region while the effect of the threshold one improves the agreement with fixed-order calculations in the medium and large- regions.
