# Quark model description of $\psi(4260)$

## TL;DR

This paper uses a quark model with a Born-Oppenheimer approximation to describe the $ ext{psi}(4260)$ resonance, successfully matching its mass and decay properties based on lattice QCD insights.

## Contribution

It introduces a novel application of the Born-Oppenheimer approximation to model the $ ext{psi}(4260)$ within a quark-antiquark potential framework, incorporating lattice indications.

## Key findings

- Accurately reproduces the mass of $ ext{psi}(4260)$
- Describes decay properties consistent with experimental data
- Supports a quark-antiquark interpretation of $ ext{psi}(4260)$

## Abstract

From lattice indications we follow a Born-Oppenheimer approximation to build a quark-antiquark static potential for $J^{PC}=1^{--}$ charmonium states below their first S- wave meson-meson threshold. We show that a good description of the mass and decay properties of the experimentally well established $\psi(4260)$ resonance is feasible.
