Charmed mesons at finite temperature and chemical potential
Fernando E. Serna, Gastão Krein
We compute the masses of the pseudoscalar mesons , and at finite temperature and baryon chemical potential. The computations are based on a symmetry- preserving D…
Bound states of a light atom and two heavy dipoles in two dimensions
D. S. Rosa, F. F. Bellotti, A. S. Jensen +2
We study a three-body system, formed by a light particle and two identical heavy dipoles, in two dimensions in the Born-Oppenheimer approximation. We present the analytic light-par…
Symmetry-preserving contact interaction model for heavy-light mesons
F. E. Serna, M. A. Brito, G. Krein
We use a symmetry-preserving regularization method of ultraviolet divergences in a vector-vector contact interac- tion model for low-energy QCD. The contact interaction is a repres…
Thermodynamics of quark matter with a chiral imbalance
R. L. S. Farias, Dyana C. Duarte, Gastão Krein +1
We show how a scheme of rewriting a divergent momentum integral can conciliate results obtained with the Nambu--Jona-Lasinio model and recent lattice results for the chiral transit…
Mesonic Decay of Charm Hypernuclei
Sabyasachi Ghosh, Carlos E. Fontoura, Gastão Krein
hypernuclei are expected to have binding energies and other properties similar to those of strange hypernuclei in view of the similarity between the quark structures of the…
Thermo-magnetic effects in quark matter: Nambu--Jona-Lasinio model constrained by lattice QCD
R. L. S. Farias, V. S. Timoteo, S. S. Avancini +2
The phenomenon of inverse magnetic catalysis of chiral symmetry in QCD predicted by lattice simulations can be reproduced within the Nambu--Jona-Lasinio model if the coupling~ o…
