Thermo-magnetic corrections to - Scattering Lengths in the Linear Sigma Model
Marcelo Loewe, Enrique Muñoz, Renato Zamora
In this article, we extend our previous study of the - scattering lengths under the presence of an external magnetic field, including finite temperature effects. The novelty…
On the critical end point in a two-flavor linear sigma model coupled to quarks
Alejandro Ayala, Luis A. Hernandez, Marcelo Loewe +2
We use the linear sigma model coupled to quarks to explore the location of the phase transition lines in the QCD phase diagram from the point of view of chiral symmetry restoration…
A new perspective for the magnetic corrections to - Scattering Lengths in the Linear Sigma Model
M. Loewe, L. Monje, E. Muñoz +2
In this article, a new perspective for obtaining the magnetic evolution of scattering lengths in the frame of the linear sigma model is presented. When computing the relevant…
Magnetic renormalons in a scalar self interacting theory
M. Correa, M. Loewe, D. Valenzuela +1
We present an analysis about the influence of an external magnetic field on renormalons in a self interacting theory . In the weak magnetic field region, using an appropria…
