Hadron Spectroscopy in the Unquenched Quark Model

TL;DR

This paper applies the unquenched quark model to study flavor asymmetry, strangeness in the proton, and meson spectra, incorporating baryon-meson components and continuum coupling effects.

Contribution

It extends the unquenched quark model to include baryon-meson components and self-energy corrections in meson spectra, providing a more comprehensive description.

Findings

Improved understanding of flavor asymmetry and strangeness in the proton.

Accurate calculations of charmonium and bottomonium spectra with continuum effects.

Demonstration of the unquenched quark model's effectiveness in hadron spectroscopy.

Abstract

We present the last applications of the unquenched quark model (UQM) to the description of flavour asymmetry and strangeness in the proton when baryon-meson components are included. In the meson sector, the UQM is used to calculate the charmonium and bottomonium spectra with self-energy corrections due to the coupling to the meson-meson continuum.
