Baryons in the unquenched quark model

TL;DR

This paper introduces an unquenched quark model incorporating sea quark effects to better understand baryon properties, focusing on spin, flavor content, magnetic moments, and beta decays of octet baryons.

Contribution

It extends the constituent quark model by including sea quark effects through a $^{3}P_{0}$ pair-creation mechanism, providing a more comprehensive description of baryon properties.

Findings

Enhanced understanding of proton spin and flavor structure

Improved predictions of magnetic moments of octet baryons

Better modeling of beta decay processes in baryons

Abstract

In this contribution, we present the unquenched quark model as an extension of the constituent quark model that includes the effects of sea quarks via a $^{3}P_{0}$ quark-antiquark pair-creation mechanism. Particular attention is paid to the spin and flavor content of the proton, magnetic moments and $\beta$ decays of octet baryons.
