Staggered Chiral Perturbation Theory for All-Staggered Heavy-Light Mesons
In HISQ simulations by the MILC and Fermilab Lattice collaborations, both the light quarks and the charm quark are staggered. We extend staggered chiral perturbation theory (S χ PT) to include such all-staggered heavy-light mesons. We assume that the heavy quark action is sufficiently improved that we may take am Q << 1 (where m Q is the heavy quark mass), but also that m Q >> Λ QCD so that a c...

متن کاملThermodynamics using Wilson and Staggered Quarks
Lattice investigations of QCD at finite temperature have contributed considerably to the current understanding of the transition from the hadronic state of matter to the quark gluon plasma and of the physics of the plasma phase. Mainly due to the ever-present limitations of computational power many analyses have been carried out in the pure gauge sector of QCD such that bulk properties of gluon...

متن کاملLight hadrons with improved staggered quarks : approaching the continuum limit
We have extended our program of QCD simulations with an improved Kogut-Susskind quark action to a smaller lattice spacing, approximately 0.09 fm. Also, the simulations with a ≈ 0.12 fm have been extended to smaller quark masses. In this paper we describe the new simulations and computations of the static quark potential and light hadron spectrum. These results give information about the remaini...
