Gauge covariant approach to the electroweak interactions of mesons in the Nambu-Jona-Lasinio model with spin-1 states
A. A. Osipov, B. Hiller, P. M. Zhang
An extended Nambu-Jona-Lasinio (NJL) model with chiral group and spin-0 and spin-1 four quark interactions is used to develop the gauge covariant approach to the…
Hadronic electroweak current and mixing
A. A. Osipov, B. Hiller, P. M. Zhang
It is found that in presence of electroweak interactions the gauge covariant diagonalization of the axial-vector -- pseudoscalar mixing in the effective meson Lagrangian leads to a…
Thermodynamical properties of strongly interacting matter in a model with explicit chiral symmetry breaking interactions
J. Moreira, J. Morais, B. Hiller +2
We analyse the effects of the light and strange current quark masses on the phase diagram of QCD at finite temperature and vanishing baryonic chemical potential, computing the spee…
Supercurrent anomaly and gauge invariance in N=1 supersymmetric Yang-Mills theory
Y. R. Batista, Brigitte Hiller, Adriano Cherchiglia +1
We analyse Feynman diagram calculational issues related to the quantum breaking of supercurrent conservation in a supersymmetric non-abelian Yang-Mills theory. For the sake of simp…
