Quenched Staggered Spectrum at Beta=6.0, 6.2 and 6.4

TL;DR

This paper reports on the hadron spectrum calculations in quenched lattice QCD at multiple beta values using staggered fermions, focusing on statistical analysis due to limited configurations.

Contribution

It provides preliminary results on the quenched hadron spectrum at different lattice spacings with an emphasis on statistical considerations.

Findings

Unable to discredit quenched QCD

Spectrum results consistent with previous studies

Highlights importance of statistical analysis in lattice QCD

Abstract

We give a preliminary report on the hadron spectrum on an ensemble of quenched lattices at $\beta$ values of 6.0, 6.2 and 6.4, using staggered fermions and collaborators Rajan Gupta and Steve Sharpe. Because of the relatively small number of configurations we pay marginally more attention to the question of statistics than in previous analyses. We are unable to discredit quenched QCD.
