A proton-pentaquark mixing and the~intrinsic charm model

Abstract

A new interpretation of intrinsic charm phenomenon based on the assumption of pentaquark $|uudc\bar{c}⟩$ 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.
