Description
Large energy Drell-Yan and $Z$-boson production data have been used to extract transverse momentum dependent parton distribution functions (TMDPDFs). Evolution of TMDPDFs is conveniently described in $b_T$ space, the Fourier conjugate to transverse momentum. The cross section depends on perturbative QCD calculations and non-perturbative TMD functions at low and high regions of the $b_T$ spectrum, respectively. The perturbative QCD description includes the operator product expansion, which has dependence on collinear PDFs. Here, we perform a Monte Carlo global QCD analysis to extract both PDFs and TMDPDFs simultaneously. We explore various TMD factorization methods from the Collins-Soper-Sterman (CSS), Qiu-Zhang (QZ), and zeta prescriptions.
