Chiral Perturbation Theory for Staggered Sea Quarks and Ginsparg-Wilson Valence Quarks
Oliver Baer, Claude Bernard, Gautam Rupak +1
We study lattice QCD with staggered sea and Ginsparg-Wilson valence quarks. The Symanzik effective action for this mixed lattice theory, including the lattice spacing contributions…
A nucleon in a tiny box
Paulo F. Bedaque, Harald W. Griesshammer, Gautam Rupak
We use Chiral Perturbation Theory to compute the nucleon mass-shift due to finite volume and temperature effects. Our results are valid up to next-to-leading order in the "\eps-reg…
Chiral perturbation theory for lattice QCD including O(a^2)
O. Baer, G. Rupak, N. Shoresh
The O(a^2) contributions to the chiral effective Lagrangian for lattice QCD with Wilson fermions are constructed. The results are generalized to partially quenched QCD with Wilson…
Chiral perturbation theory at O(a^2) for lattice QCD
Oliver Baer, Gautam Rupak, Noam Shoresh
We construct the chiral effective Lagrangian for two lattice theories: one with Wilson fermions and the other with Wilson sea fermions and Ginsparg-Wilson valence fermions. For eac…
Simulations with different lattice Dirac operators for valence and sea quarks
O. Baer, G. Rupak, N. Shoresh
We discuss simulations with different lattice Dirac operators for sea and valence quarks. A goal of such a "mixed" action approach is to probe deeper the chiral regime of QCD by en…
Chiral perturbation theory for the Wilson lattice action
Gautam Rupak, Noam Shoresh
We extend chiral perturbation theory to include linear dependence on the lattice spacing for the Wilson action. The perturbation theory is written as a double expansion in the…
