# Kaons and antikaons in strong magnetic fields

## TL;DR

This paper investigates how strong magnetic fields affect the in-medium masses of kaons and antikaons in asymmetric nuclear matter using a chiral SU(3) model, highlighting the roles of nucleon interactions, Landau levels, and anomalous magnetic moments.

## Contribution

It introduces a comprehensive study of kaon and antikaon mass modifications in magnetized nuclear matter, including effects of Landau levels and nucleon anomalous magnetic moments.

## Key findings

- Density effects dominate mass modifications.
- Magnetic field and isospin effects are significant at high densities.
- Anomalous magnetic moments influence meson masses at high magnetic fields.

## Abstract

The in-medium masses of the kaons and antikaons in strongly magnetized asymmetric nuclear matter are studied using a chiral SU(3) model. The medium modifications of the masses of these open strange pseudoscalar mesons arise due to their interactions with the nucleons and scalar mesons within the model. The proton, the charged nucleon, has effects from the Landau energy levels in the presence of the magnetic field. The anomalous magnetic moments (AMM) of the nucleons are taken into consideration in the present study and these are seen to be large at high magnetic fields and high densities. The isospin effects are appreciable at high densities. The density effects are observed to be the dominant medium effects, as compared to the effects from magnetic field and isospin asymmetry. ~
