20. Lattice-to-continuum factorization for TMDs

Non-perturbative parton distributions that arise in the factorization of cross-sections are inaccessible to direct lattice QCD calculations, as their lightcone-dominated dynamics induce a real-time sign problem. One may circumvent this issue by constructing a lattice-calculable distribution that shares the same IR physics as the desired physical distribution, and then connecting the two...

31. Simultaneous extraction of collinear and transverse momentum dependent parton densities using Drell-Yan data

Drell-Yan production data have been used to extract transverse momentum dependent parton distribution functions (TMDPDFs). The evolution of these non-perturbative objects is conveniently described in $b_T$ space, which is the Fourier conjugate to transverse momentum. Both perturbative QCD calculations and non-perturbative TMD functions comprise the Drell-Yan cross section at low and high...
