Exotic and Non-Exotic Baryon Properties on the Light Cone

TL;DR

This paper investigates the static properties of light exotic and non-exotic baryons using the light-cone formulation of the chiral quark-soliton model, emphasizing the role of Fock components and pion cloud effects.

Contribution

It provides a comprehensive analysis of baryon properties including vector, axial, tensor charges, and electromagnetic moments within a light-cone framework, considering up to seven-quark Fock states.

Findings

Fock components up to seven-quark sector significantly influence baryon properties.

Pion cloud contributions are substantial in the static observables.

Decomposition of observables into flavor, valence, sea, and antiquark contributions enhances understanding.

Abstract

We present an extensive study of the static properties of light exotic and non-exotic baryons, based on the formulation of chiral quark-soliton model in terms of light-cone wave functions. We discuss in particular vector, axial and tensor charges as well as an estimation of the electromagnetic moments for the baryon octet, decuplet and hypothetical antidecuplet. Contributions from Fock components up to the seven-quark sector are considered and appear to be sizeable, reflecting the importance of the pion cloud. All these observables are further decomposed into flavor, valence quark, sea quark and antiquark contributions.
