Description
In this work, we incorporate transverse momentum dependent (TMD) non-perturbative (NP) effects into the RadISH framework.
By accounting for these effects, we achieve an improvement in the theoretical description of the Drell-Yan cross section at low $p_{T, \ell \ell}$ (the transverse momentum of the final-state lepton pair).
A similar effect is observed in the $\phi_{\eta}^*$ differential cross section, where $\phi_{\eta}^*$ is a variable sensitive to the angular separation between the two outgoing leptons.
The inclusion of NP effects in RadISH is expected to play a significant role in the analysis of high-energy particle collisions.
