Light hadron properties with improved staggered quarks

TL;DR

This paper presents preliminary lattice QCD results for light hadron properties using improved staggered quarks, analyzing the continuum limit and quark mass dependence of pseudoscalar mesons.

Contribution

It provides new insights into the continuum extrapolation and quark mass effects in lattice simulations with 2+1 flavors using improved staggered quarks.

Findings

Approach to the continuum limit is examined.

Dependence of pseudoscalar masses on sea and valence quark masses analyzed.

Results suggest improved staggered quarks effectively capture light hadron properties.

Abstract

Preliminary results from simulations with 2+1 dynamical quark flavors at a lattice spacing of 0.09 fm are combined with earlier results at a=0.13 fm. We examine the approach to the continuum limit and investigate the dependence of the pseudoscalar masses and decay constants as the sea and valence quark masses are separately varied.
