Kaon structure modifications in strange hadronic matter

TL;DR

This paper investigates how the internal structure of kaons changes in dense strange hadronic matter, revealing modifications in electromagnetic form factors and charge distributions due to medium effects.

Contribution

It introduces a novel analysis of in-medium kaon structure using the light-cone quark model combined with effective quark masses from the chiral SU(3) model, accounting for density and strangeness.

Findings

Kaon electromagnetic form factors are suppressed in dense strange matter.

Charge density within kaons is redistributed at high densities.

Medium effects significantly alter kaon internal structure.

Abstract

We present the valence quark distributions of the kaons in an isospin asymmetric dense strange medium consisting of nucleons and hyperons. The comparative analysis of in-medium parton distribution functions, electromagnetic form factors, and charge densities with respect to the free space distributions is studied in the light-cone quark model. The medium effects are incorporated in these distribution functions by using the effective quark masses, computed from the chiral SU(3) quark mean field model for finite values of baryonic density, isospin asymmetry, and strangeness fraction parameters. We observe a suppression of the kaon electromagnetic form factors and a redistribution of charge density in high-density strange matter.
