The nature of the resonances from a coupled-channels approach
Pablo G. Ortega, Jorge Segovia
The positive parity charmonium states are expected to lie around the 3.9 GeV/ energy region, according to the predictions of quark models. However, a plethora of…
Does count?
Pablo G. Ortega, Enrique Ruiz Arriola
The question on whether or not weakly bound states should be effectively incorporated in a hadronic representation of the QCD partition function is addressed by analyzing the examp…
Bottom and Charm Quark Mass Determination from Quarkonium at NLO
Pablo G. Ortega, Vicent Mateu
The non-perturbative nature of QCD at hadronic scales implied the development of phenomenological approaches such as quark models or, more recently, computer-based calculations usi…
Threshold effects in hadron spectrum: a new spectroscopy?
Pablo G. Ortega, Jorge Segovia, David R. Entem +1
The exploration of energies above the open-flavor threshold in the meson spectra has led to the appearance of unexpected states difficult to accommodate in the naive picture of a b…
Bottom and Charm Mass determinations from global fits to bound states at NLO
Vicent Mateu, Pablo G. Ortega
The bottomonium spectrum up to is studied within Non-Relativistic Quantum Chromodynamics up to NLO. We consider finite charm quark mass effects both in the QCD potentia…
Counting states and the Hadron Resonance Gas: Does X(3872) count?
Pablo G. Ortega, David R. Entem, Francisco Fernandez +1
We analyze how the renowned X(3872), a weakly bound state right below the threshold, should effectively be included in a hadronic representation of the QCD partition f…
Charmonium resonances in the 3.9 GeV/ energy region and the puzzle
Pablo G. Ortega, Jorge Segovia, David R. Entem +1
An interesting controversy has emerged challenging the widely accepted nature of the and the resonances, which had initially been assigned to the a…
