The impact of transverse Slavnov-Taylor identities on dynamical chiral symmetry breaking
Luis Albino, Adnan Bashir, Bruno El-Bennich +3
We extend earlier studies of transverse Ward-Fradkin-Green-Takahashi identities in QED, their usefulness to constrain the transverse fermion-boson vertex and their importance for m…
Transport responses from rate of decay and scattering processes in the Nambu--Jona-Lasinio model
Sabyasachi Ghosh, Fernando E. Serna, Aman Abhishek +2
We have calculated quark and anti-quark relaxation time by considering different possible elastic and inelastic scatterings in the medium. Comparative role of these elastic and ine…
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…
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…
Shear and Bulk Viscosities of Quark Matter from Quark-Meson Fluctuations in the Nambu--Jona-Lasinio model
Sabyasachi Ghosh, Thiago C. Peixoto, Victor Roy +2
We have calculated the temperature dependence of shear and bulk viscosities of quark matter due to quark-meson fluctuations. The quark thermal width originating from quantu…
