Coupling hadron-hadron thresholds within a chiral quark model approach
Pablo G. Ortega, David R. Entem
Heavy hadron spectroscopy was well understood within the naive quark model until the end of the past century. However, in 2003, the was discovered, with puzzling properti…
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…
Weak B Decays into Orbitally Excited Charmed Mesons
J. Segovia, C. Albertus, D. R. Entem +3
The BaBar Collaboration has recently reported branching fractions for semileptonic decays of the meson into final states with charged and neutral and $D_{2}^{\ast…
Spectroscopy of mesons and the possibility of finding exotic -like structures
Pablo G. Ortega, Jorge Segovia, David R. Entem +1
The bottom-charmed () mesons are more stable than their charmonium () and bottomium () partners because they cannot annihilate into gluons. However, the low…
