Parity realization in Vector-like theories from Fermion Bilinears
V. Azcoiti, G. di Carlo, A. Vaquero
We reconsider in this paper the old aim of trying to understand if the observed realization of discrete symmetries as Parity or CP in the QCD vacuum can be satisfied from first pri…
Theta-vacuum: Phase Transitions and/or Symmetry Breaking at
V. Azcoiti, A. Galante, V. Laliena
Assuming that a quantum field theory with a -vacuum term in the action shows non-trivial -dependence and provided that some reasonable properties of the probability distribut…
Vector Symmetries and Theta-Vacuum
V. Azcoiti, A. Galante
Under very general assumptions we show that Vafa-Witten theorem on vector symmetries in vector-like theories can be extended to some physically relevant gauge theories with non-pos…
Parity and CT realization in QCD
Vicente Azcoiti, Angelo Galante
We show that an essential assumption in the Vafa and Witten's theorem on P and CT realization in vector-like theories, the existence of a free energy density in Euclidean space in…
Spontaneous Symmetry Breaking in Fermion-Gauge Systems- A Non Standard Approach
Vicente Azcoiti, Victor Laliena, Xiang-Qian Luo
We propose a new method for the study of the chiral properties of the ground state in QFT's based on the computation of the probability distribution function of the chiral condensa…
