TL;DR
This paper introduces a new highly improved staggered fermion action that exhibits better perturbative behavior and reduces flavor mixing, enhancing lattice QCD simulations.
Contribution
The paper presents a novel fermion action with improved perturbative properties and reduced flavor mixing compared to conventional methods.
Findings
Perturbative calculations are well-behaved with the new action.
The new terms help control flavor mixing.
Design of operators is discussed for the improved action.
Abstract
We present a new action for highly improved staggered fermions. We show that perturbative calculations for the new action are well-behaved where those of the conventional staggered action are badly behaved. We discuss the effects of the new terms in controlling flavor mixing, and discuss the design of operators for the action.
