Constituent-quark-model based coupled-channels calculation of the and tetraquark systems
Pablo G. Ortega, David R. Entem, Francisco Fernández +1
We perform a coupled-channels study of the and tetraquark systems in a molecular approach using a constituent quark model which has been widely us…
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…
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…
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…
A chiral quark model analysis of the interaction
M. Conde-Correa, T. Aguilar, A. Capelo-Astudillo +3
In this work we analyze the interaction in the framework of a constituent quark model. The near-threshold elastic and charge exchange cross sections are evaluated, findin…
Exploring doubly-heavy tetraquarks in constituent-quark-model based meson-meson coupled-channels approach
P. G. Ortega, D. R. Entem, F. Fernandez +1
The LHCb Collaboration announced in 2021 the discovery of a new tetraquark-like state, named , with minimum quark content , close to the thres…
An assessment of -states above -threshold using a constituent-quark-model based meson-meson coupled-channels framework
P. G. Ortega, D. R. Entem, F. Fernández +1
The state has been recently observed by the Belle and Belle~II collaborations with enough global significance to motivate an assessment of the high-energy spectrum usual…
Microscopic Model of Charmonium Strong Decays
J. Segovia, D. R. Entem, F. Fernández
Although the spectra of heavy quarkonium systems has been successfully explained by certain QCD motivated potential models, their strong decays are difficult to deal with. We perfo…
Molecular components in and mesons
Pablo G. Ortega, Jorge Segovia, David R. Entem +1
Different experiments have confirmed that the and mesons are very narrow states located, respectively, below the and threshold…
Strong charmonium decays in a microscopic model
J. Segovia, D. R. Entem, F. Fernandez
Although the spectra of heavy quarkonium systems have been successfully explained by certain QCD motivated potential models, their strong decays are still an open problem. We perfo…
