Contribution

It extends the logarithmic quark-sigma model to include strange quarks and analyzes their impact on chiral symmetry breaking in magnetic backgrounds.

Findings

Chiral symmetry breaking is sensitive to strange quark flavor.

The magnetic field influences symmetry breaking differently with strange quarks.

Comparison shows differences from the original sigma model.

Abstract

The chiral symmetry breaking in the presence of an external magnetic field is studied in the framework of logarithmic quark-sigma model with three flavors (u,d,s). The effective logarithmic mesonic potential is extended to strange quark and is numerically solved in the mean-field approximation. The present results show that the chiral symmetry breaking is sensitive for the strange quark flavour in the presence an external magnetic field. In addition, the effect of the free parameters is studied. A comparison with original sigma model is discussed.
