# A systematic study of mass spectra and strong decay of strange mesons

## TL;DR

This paper analyzes the mass spectrum and strong decay properties of strange mesons, especially kaons, using a modified quark model to identify observed states and predict properties of unobserved ones, aiding future experimental searches.

## Contribution

It introduces a modified Godfrey-Isgur model with color screening to systematically study kaon spectra and decay behaviors, providing new assignments and decay predictions.

## Key findings

- Identification of possible kaon states and their structures.
- Predictions of decay widths for missing kaon states.
- Comparison of theoretical decay results with experimental data.

## Abstract

The mass spectrum of the kaon family is analyzed by the {modified} Godfrey-Isgur model with a color screening effect approximating the kaon as a heavy-light meson system. This analysis gives us the structure and possible assignments of the observed kaon candidates, which can be tested by comparing the theoretical results of their two-body strong decays with the experimental data. Additionally, prediction of some partial decay widths is made on the kaons still missing in experiment. This study is crucial to establishing the kaon family and searching for their higher excitations in the future.
