# Numerical Evidence for the Observation of a Scalar Glueball

## TL;DR

This paper uses lattice QCD calculations to predict the decay widths of the lightest scalar glueball, supporting its identification with the observed meson $f_J(1710)$ and providing insights into its properties.

## Contribution

The study provides the first lattice QCD predictions for the decay widths of the scalar glueball in the quenched approximation, linking theoretical results with experimental observations.

## Key findings

- Decay widths align with the properties of $f_J(1710)$
- Scalar glueball mass predictions match previous lattice results
- Results challenge alternative meson resonance identifications

## Abstract

We compute from lattice QCD in the valence (quenched) approximation the partial decay widths of the lightest scalar glueball to pairs of pseudoscalar quark-antiquark states. These predictions and values obtained earlier for the scalar glueball's mass are in good agreement with the observed properties of $f_J(1710)$ and inconsistent with all other observed meson resonances.
