Determination of transverse momentum dependent parton distribution functions from deep-inelastic scattering and Drell-Yan data within the Paton Branching approach. 15/07/2021 - 14/07/2022

Abstract

Searches for phenomena beyond the Standard Model of particle physics require precision predictions of final states observed in high-energy particle collisions. One of the main sources of uncertainty in theoretical predictions originates from parton distribution functions, whose evolution is described by quantum chromodynamics. The "Parton Branching method", which was recently developed by the UAntwerp team and their collaborators, allows to improve upon the state-of-the-art approach based on collinear factorization by including the transverse degrees of freedom of partons inside hadrons. With this project, we propose to apply this method and obtain fits of transverse momentum dependent parton densities to deep inelastic scattering and Drell-Yan production data obtained at the HERA and LHC colliders. These new fits will incorporate color coherence through a dynamical soft gluon resolution scale and will use transverse momentum dependent splitting functions, ultimately leading to an increased precision of theoretical predictions.
