$K^{+}$ and $K^{-}$ potentials in hadronic matter can be observed

TL;DR

This paper proposes that low transverse momentum K+ and K- spectra in light symmetric systems at 2 AGeV can be used to directly determine the potentials of these kaons in hadronic matter.

Contribution

It introduces a method to extract K+ and K- potentials from spectral ratios in heavy-ion collisions at low energies.

Findings

Spectral ratios are sensitive to K potential strengths.

Potential determination can be achieved through experimental spectral measurements.

The approach provides a direct way to probe kaon interactions in hadronic matter.

Abstract

We aim to show that K+ and K- spectra at low transverse momentum measured in light symmetric systems at around 2AGeV depend strongly on the K potential. The ratio of the spectra can allow therefore for a direct determination of the strength of the K+ as well as that of the K- potential in a hadronic environment.
