Canonical interpretation of the $X(4140)$ state within the $^3P_0$ model

TL;DR

This paper investigates whether the $X(4140)$ state can be interpreted as the $ ext{chi}_{c1}(3P)$ charmonium state by analyzing its mass and decay properties within the $^3P_0$ model, addressing recent experimental uncertainties.

Contribution

Findings

Supports the $ ext{chi}_{c1}(3P)$ interpretation based on decay properties.

Addresses the discrepancy in the width measurements of $X(4140)$.

Offers insights into the nature of the $X(4140)$ state.

Abstract

Recently, LHCb collaboration has confirmed the state $X(4140)$, with a much larger width $\Gamma= 83\pm 21^{+21}_{-14}$ MeV than the previous experimental measurements, which has confused the understanding of its nature. We have investigated the possibility of the $\chi_{c1}(3P)$ interpretation for the $X(4140)$, considering the mass and the strong decay properties.
