TL;DR
This paper calculates the mass of the singlet 0++ particle in lattice QCD using two different operators, providing insights into its properties within the theory.
Contribution
It introduces a lattice QCD approach combining (psi_bar psi) and Wilson loop operators to determine the singlet 0++ particle mass.
Findings

Comparison of operator effectiveness in mass calculation
Enhanced understanding of scalar meson properties
Abstract
We compute the mass of the singlet 0++ state using both (psi_bar psi) and Wilson loop operators from a N_f=2 lattice QCD calculation.
