Improved Hessian Method in Global Analysis of Parton Distribution Functions
Wenxiao Zhan, Siqi Yang, Minghui Liu +3
The Hessian method is widely applied in the global analysis of parton distribution functions (PDFs), which uses a set of orthogonal eigenvectors to give predictions of a physical o…

A -ratio observable for studies of intrinsic transverse momentum of partons from Drell-Yan spectra
Wenxiao Zhan, Siqi Yang, Minghui Liu +2
The determination of the intrinsic transverse momentum distribution of partons is central both for applications of parton shower Monte Carlo generators and for QCD studies of trans…

Coarse-grained binning in Drell-Yan transverse momentum spectra
Wenxiao Zhan, Siqi Yang, Minghui Liu +2
We report a study of the determination of the intrinsic transverse momentum of partons, the intrinsic , from the dilepton transverse momentum in Drell-Yan (DY) productio…
