چکیده

Scale setting for QCD with two flavors of staggered quarks is examined using Wilson flow over a factor of four change in both the lattice spacing and the pion mass. The statistics needed to keep the errors in the flow scale fixed is found to increase approximately as the inverse square of the lattice spacing. Tree level improvement of the scales t0 and w0 is found to be useful in most of the range of lattice spacings we explore. The scale uncertainty due to remaining lattice spacing effects is found to be about 3%. The ratio w0= ffiffiffiffi t0 p is Nf dependent and we find its continuum limit to be 1.106 0.007ðstatÞ 0.005ðsystÞ for mπw0 ≃ 0.3.

PQChPT with Staggered Sea and Valence Ginsparg-Wilson Quarks: Vector Meson Masses

We consider partially quenched, mixed chiral perturbation theory with staggered sea and Ginsparg-Wilson valence quarks in order to extract a chiral-continuum extrapolation expression for the vector meson mass up to order O(a2), at one-loop level. Based on general principles, we accomplish the task without explicitly constructing a sophisticated, heavy vector meson chiral Lagrangian. PACS number...

Baryons with Ginsparg-Wilson quarks in a staggered sea

Department of Physics Duke University P.O. Box 90305 Durham, NC 27708-0305 (Dated: August 24, 2005) Abstract We determine the masses and magnetic moments of the octet baryons in chiral perturbation theory formulated for a mixed lattice action of Ginsparg-Wilson valence quarks and staggered sea quarks. Taste-symmetry breaking does not occur at next-to-leading order in the combined latticespacing...

Towards the continuum limit with quenched staggered

We extend previous work on nite-size eeects with dynamical staggered quarks to the quenched approximation. We again emphasize the large volume limit that is of interest for spectrum calculations which may hope to approach the experimental values. Relying on new calculations at 6=g 2 = 5:7 and recent work with weaker couplings, we extrapolate to the continuum limit and nd a nucleon to rho mass r...

On the Dynamics of Light Quarks in QCD

We describe recent results concerning the behavior of lattice QCD with light dynamical Wilson and Staggered quarks. We show that it is possible to reach regions of parameter space with light pions m 0:2=a using Wilson fermions. If the Hybrid Molecular Dynamics (HMD) algorithm is used with the same parameters it gives incorrect results. We also present preliminary results using a higher-order in...
