Charmonium decay in the C3P0 Model

TL;DR

This paper employs the $C^3P_0$ model to calculate decay widths of low-lying charmonium states, providing theoretical predictions for various decay channels relevant to understanding charmonium decay mechanisms.

Contribution

The study applies the $C^3P_0$ model specifically to charmonium states, offering new decay width calculations for several important decay channels.

Findings

Calculated decay widths for $J/ ext{psi}(1S)$ and $ ext{psi}(2S)$ in multiple channels.

Provided theoretical predictions that can be tested against experimental data.

Enhanced understanding of charmonium decay processes using the $C^3P_0$ model.

Abstract

In this work, we use the $C^3P_{\,0}$ model to calculate the decay widths of the low lying charmonium $J^{PC}=1^{--}$ states, nominally $J/\psi(1S)$ and $\psi(2S)$, in the following common channels: $\rho\,\pi$, $\omega\,\eta$, $\omega\,\eta^\prime$, $K^{\ast +}\,K^-$, $K^{\ast 0}\,\bar{K}^0$, $\phi\,\eta$, $\phi\,\eta^\prime$.
