A bstract We perform a complete calculation of the pion-kaon scattering amplitude in Chiral
Perturbation Theory at finite temperature, paying particular attention to the analytic structure …

We present calculations of the S-wave isospin-zero and isospin-two pion-pion scattering
lengths within a nucleon-meson model with parity doubling. Both scattering lengths are …

In this article, we consider the magnetic corrections to π-π scattering lengths in the frame of
the linear sigma model. For this, we consider all the one-loop corrections in the s, t, and u …

We calculate the thermal evolution of π-π scattering lengths, in the framework of the Nambu–
Jona-Lasinio model. The thermal corrections were calculated at the one-loop level using …

In this article, a new perspective for obtaining the magnetic evolution of π-π scattering
lengths in the linear sigma model is presented. When computing the relevant one-loop …

In this article, we extend our previous study of the π-π scattering lengths under the presence
of an external magnetic field, including finite temperature effects. The novelty of this work is …

A procedure for implementation of the generating equations in the linear sigma model of low
energy QCD is presented. For any explicit symmetry breaking term, this procedure computes …

We present a discussion of the behavior of π-π scattering lengths under the presence of an
external magnetic field, including also finite temperature effects. In this way, we are able to …
