Abstract
We perform a comparison of the impact of different intrinsic charm (IC) models, based on the prediction of the differential cross-sections of [Formula: see text]-boson and [Formula: see text]-jet production in [Formula: see text] collision. It is shown that regardless of choosing the model, considering nonperturbative intrinsic charm component increases the magnitude of the cross-section when the [Formula: see text] transverse momentum grows or at large rapidity [Formula: see text] of the [Formula: see text]. Moreover, to evaluate the effect of different parton distribution functions (PDFs), we also compare the results of two PDF sets in prediction of production [Formula: see text]-jet in [Formula: see text] at a center-of-mass energy of 13 TeV with taking into account the intrinsic charm contribution in the proton. It is shown that the various PDF sets give some difference in the description of the [Formula: see text]-jet cross-section.
