Topological susceptibility with three flavors of staggered quarks
C. Aubin, C. Bernard, Brian Billeter +8
As one test of the validity of the staggered-fermion fourth-root determinant trick, we examine the suppression of the topological susceptibility of the QCD vacuum in the limit of s…

Topological susceptibility in staggered fermion chiral perturbation theory
Brian Billeter, Carleton DeTar, James Osborn
The topological susceptibility of the vacuum in quantum chromodynamics has been simulated numerically using the Asqtad improved staggered fermion formalism. At nonzero lattice spac…
