A proton-pentaquark mixing and the~intrinsic charm model

TL;DR

This paper proposes a new interpretation of the intrinsic charm phenomenon by modeling it as a mixing between a proton and a pentaquark state, supported by theoretical analysis and experimental data.

Contribution

It introduces a novel pentaquark mixing model for intrinsic charm and constructs the structure function of the charm quark within this framework.

Findings

The pentaquark mixing model explains intrinsic charm phenomena.

The structure function of the charm quark in the pentaquark is explicitly constructed.

Experimental data supports the proposed mixing mechanism.

Abstract

A new interpretation of intrinsic charm phenomenon based on the assumption of pentaquark $\left| u u d c\bar{c} \right>$ mixing with a proton is offered. The structure function of the $c$-quark in the pentaquark is constructed. Mixing different states is considered theoretically and using experiment data on $D$-meson production and inclusive production of the hidden charm particles.
