Hadron Spectrum in QCD with Valence Wilson Fermions and Dynamical Staggered Fermions at $6/g^2=5.6

TL;DR

This paper analyzes hadronic spectra in lattice QCD using Wilson valence quarks and dynamical staggered fermions, comparing results across different lattice sizes and quark masses to understand spectral properties.

Contribution

It provides a detailed comparison of hadronic spectroscopy results between different fermion formulations and lattice sizes in lattice QCD simulations.

Findings

Spectral results are consistent across lattice sizes.

Valence Wilson fermions show expected behavior with dynamical staggered sea.

Comparison highlights effects of lattice size and fermion formulation on spectra.

Abstract

We present an analysis of hadronic spectroscopy for Wilson valence quarks with dynamical staggered fermions at lattice coupling $6/g^2 = \beta=5.6$ at sea quark mass $am_q=0.01$ and 0.025, and of Wilson valence quarks in quenched approximation at $\beta=5.85$ and 5.95, both on $16^3 \times 32$ lattices. We make comparisons with our previous results with dynamical staggered fermions at the same parameter values but on $16^4$ lattices doubled in the temporal direction.
