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…

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…

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…
