Description

We present new phenomenological studies of the impact of a recently suggested formalism that simultaneously resums logarithmic contributions that are enhanced at small $p_T$ and large $x$. This formalism relies on the combination of a so-called threshold-improved transverse momentum and threshold resummation which allows for a systematic improvement of the transverse momentum resummation that is valid in the entire range of $p_T$. As a phenomenological application, we consider the Higgs boson production at LHC where we show that threshold-improved transverse momentum resummation leads to faster perturbative concergence at small-$p_T$ while the inclusion of threshold resummation improves the agreement with fixed-order calculations.
