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…
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…
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…
Excited hadrons and the analytical structure of bound-state interaction kernels
Bruno El-Bennich, Gastão Krein, Eduardo Rojas +1
We highlight Hermiticity issues in bound-state equations whose kernels are subject to a highly asymmetric mass and momentum distribution and whose eigenvalue spectrum becomes compl…
