Thermomagnetic corrections to π-π scattering lengths in the linear sigma model

Loewe, M; Muñoz, E.; Zamora, R

Keywords: Thermal and magnetic corrections, Linear sigma model, Pi-Pi scattering


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 precisely the introduction of temperature into the discussion and its interplay with the magnetic field. As in the previous article, we base our analysis in the linear sigma model, and our calculations are exact within this context. Although the effects are comparatively small, it is interesting to remark that the magnetic field and temperature display opposite effects over the scattering lengths.
