Testing the molecular nature of $\phi(2170)$

TL;DR

This paper investigates the molecular structure of the $(2170)$ particle by calculating its decay widths into specific kaon-related final states and comparing the results with experimental data from BESIII.

Contribution

It provides a theoretical analysis of $(2170)$ as a molecular state and offers decay width predictions that align with recent experimental findings.

Findings

Decay width ratios are consistent with BESIII results.

Supports the molecular interpretation of $(2170)$.

Provides specific predictions for decay channels involving $K(1460)$, $K_1(1270)$, and $K_1(1400)$.

Abstract

In this talk we show our recent results on the decay widths of $\phi(2170)$ to final states formed by an anti-Kaon and a Kaonic resonance, in particular, $K(1460)$, $K_1(1270)$ and $K_1(1400)$, considering a molecular description for $\phi(2170)$. Branching fraction ratios are obtained and compared with the recent results found by the BESIII collaboration, finding compatible results.
