Global study of nuclear modifications on parton distribution functions

Understand

A global analysis of nuclear medium modifications of parton distributions is presented using deeply inelastic scattering data of various nuclear targets.

• Two obtained data sets are provided for quark and gluon nuclear modification factors, referred as nIMParton16.
• One is from the global fit only to the experimental data of isospin-scalar nuclei (Set A), and the other is from the fit to all the measured nuclear data (Set B).
• The scale-dependence is described by DGLAP equations with nonlinear corrections in this work.
