Deeply Bound Kaonic Clusters

TL;DR

This paper reviews the current theoretical and experimental understanding of deeply bound kaonic clusters, exploring their nuclear and mesonic states, and discusses recent developments explaining certain observed resonances.

Contribution

It provides a comprehensive review of deeply bound kaonic states and introduces new theoretical insights into their relation with observed resonances like X(2175) and Y(4260).

Findings

Deeply bound kaonic states have potential nuclear and mesonic structures.

Novel models explain properties of X(2175) and Y(4260) resonances.

Recent experimental data supports the existence of these bound states.

Abstract

In this talk I make a review on the theoretical and experimental situation around the deeply bound kaon clusters, the possible bound kaonic states of nuclear, rather than atomic nature. At the same time I discuss novel developments around other kind of bound kaon clusters, which include states of two mesons and one baryon, with either one or two kaons, and states of a vector meson and two kaons, which explain naturally the observed properties of the X(2175) and Y(4260) resonances.
