Proton Sea Quark Flavour Asymmetry and Roper Resonance

preprint2011arXivOpen access

Abstract

We study the proton and the Roper resonance together with the meson cloud model, by constructing a Hamiltonian matrix and solving the eigenvalue equation. The proton sea quark flavour asymmetry and some properties of the Roper resonance are thus reproduced in one scheme.
