Comparison studies of finite momentum correlators on anisotropic and isotropic lattices - art. no. 055002

We study hadronic two- and three-point correlators relevant for heavy to li ght pseudoscalar meson semileptonic decays, using Symanzik improved glue, a D234 light quark, and nonrelativistic QCD heavy quark actions. Detailed co mparisons are made between simulations on anisotropic and isotropic lattice s involving finite momentum hadrons. We find evidence that having an anisot ropy helps in extracting better signals at higher momenta. Initial results for the form factors f(+)(q(2)) and f(0)(q(2)) are presented with tree-leve l matching of the lattice heavy-light currents.
