Bootstrapping Two-Nucleon Effective Field Theories

Q. N. Micha-Mba, M. S. Sánchez, P. G. Ortega +2

Chiral EFT yields singular potentials that require regularization and renormalization when implemented in a dynamical equation such as the Lippmann--Schwinger equation. We employ t…

Exploring tetraquark candidates in a coupled-channels formalism

P. G. Ortega, D. R. Entem, F. Fernandez +1

We investigate the spectrum of tetraquark candidates within a coupled-channels framework. The analysis includes all combinations of , , $η_b(1S…

Can one-loop corrections to the one-gluon exchange potential adequately describe the charmed meson spectrum?

A. Capelo-Astudillo, T. Aguilar, M. Conde-Correa +3

We investigate the charmed meson spectrum using a constituent quark model (CQM) with one-loop corrections applied to the one-gluon exchange (OGE) potential. The study aims to under…

The Constituent Quark Model

D. R. Entem, F. Fernández, P. G. Ortega +1

In this chapter we give a pedagogical introduction to the constituent quark model. The explanation of magnetic moments of the nucleons was crucial to introduce an effective quark m…

Revisiting the proton-antiproton scattering using a constituent-quark-model based coupled-channels calculation

P. G. Ortega, D. R. Entem, F. Fernandez +1

Motivated by the last experimental and theoretical advances in the analysis of possible baryonium resonances, the and their partners, we perform a constituent-quark-model…
