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 , , , a…
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…
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…
Study of the and dibaryons in constituent quark model
Pablo Martín-Higueras, David R. Entem, Pablo G. Ortega +2
Dibaryons are the simplest system in which the baryon-baryon interaction, and hence the underlying quark-quark interaction, can be studied in a clear way. Although the only dibaryo…
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…
