Description
In this talk, we extend the study of low-invariant-mass Drell–Yan production over the full transverse-momentum spectrum, combining transverse-momentum resummation at small $q_T$ with fixed-order perturbative calculations at large $q_T$, together with a phenomenological description of non-perturbative effects.
We first consider proton–proton scattering as a benchmark to validate the approach. We then apply the same framework to pion-induced Drell–Yan processes, employing a pion non-perturbative input motivated by recent phenomenological models. This allows us to provide predictions for the transverse-momentum spectrum of low-mass Drell–Yan pair production in pion-induced reactions.
