On the role of soft and non-perturbative gluons in collinear parton densities and parton shower event generators

open access: yesEuropean Physical Journal C: Particles and Fields
The Parton Branching method offers a Monte Carlo solution to the DGLAP evolution equations by incorporating Sudakov form factors. In this approach, the Sudakov form factor can be divided into perturbative and non-perturbative components, with the non ...

Update of MRST parton distributions. [PDF]

open access: yes, 2002
We discuss the latest update of the MRST parton distributions in response to the most recent data. We discuss the areas where there are hints of difficulties in the global fit, and compare to some other updated sets of parton distributions, particularly ...

Quasi-parton distribution functions, momentum distributions, and pseudo-parton distribution functions

open access: yesPhysical Review D, 2017
We show that quasi-parton distribution functions (quasi-PDFs) may be treated as hybrids of PDFs and primordial rest-frame momentum distributions of partons. This results in a complicated convolution nature of quasi-PDFs that necessitates using large ${p}_{3}\ensuremath{\gtrsim}3\text{ }\text{ }\mathrm{GeV}$ momenta to get reasonably close to the PDF ...
