It was shown recently that standard resummation of logarithms of $Q/p_T$ canbe supplemented with the resummation of logarithmic contributions at large$x=Q^2/s$ in the case of a colourless final state such as Higgs produced viagluon fusion or the production of a lepton pair via Drell--Yan mechanism. Suchan improved transverse momentum resummation takes into account soft emissionsthat are emitted at very small angles. We report on recent phenomenologicalstudies of a combined threshold-improved $p_T$ and threshold resummationformalism to the Higgs boson produced at the LHC where small-$p_T$ andthreshold logarithms are resummed up to NNLL and NNLL* respectively. We showthat the effect of the modified $p_T$ resummation yields a faster perturbativeconvergence in the small-$p_T$ region while the effect of the threshold oneimproves the agreement with fixed-order calculations in the medium andlarge-$p_T$ regions.
