We investigate the charged-neutral difference in the pion self-energy at finite temperature T. Within chiral perturbation theory (ChPT) we extend a previous analysis performed in the chiral and soft pion limits. Our analysis with physical pion m[...]texto impreso

We analyze quark condensates and chiral (scalar) susceptibilities including isospin-breaking effects at finite temperature T. These include m(u) not equal m(d) contributions as well as electromagnetic (e not equal 0) corrections, both treated in[...]texto impreso
We analyze the isospin-breaking corrections to quark condensates within one-loop SU(2) and SU(3) chiral perturbation theory including m(u) not equal m(d) as well as electromagnetic (EM) contributions. The explicit expressions are given and sever[...]texto impreso
Making a thermal analysis in the context of NLO SU(3) Chiral Perturbation Theory we see that isospin breaking (1B) corrections (both electromagnetic and QCD ones) to quark condensates are of order beta(e(2)) and beta(epsilon) with epsilon the pi[...]texto impreso
We have performed a thermal analysis of the light scalar susceptibilities in the context of SU(3)-Chiral Perturbation Theory to one loop taking into account the QCD source of isospin breaking (IB), i.e corrections coming from m(u) not equal m(d)[...]texto impreso
We make a thermal analysis of the light scalar susceptibilities using SU(3)-chiral perturbation theory to one-loop order, taking into account the QCD source of isospin breaking (IB), i.e. corrections coming from m(u) not equal m(d). The value of[...]
