Fermionic correlation functions from the staggered Schrödinger functional

AuthorsPérez Rubio, Paula; Sint, Stefan
Issue Date29-Jan-2010
AbstractWe consider the Schrödinger functional with staggered one-component fermions on a fine lattice of size (L/a)3 ×(T/a) where T/a must be an odd number. In order to reconstruct the fourcomponent spinors, two different set-ups are proposed, corresponding to the coarse lattice having size (L/2a)3 ×(T′/2a), with T′ = T ±a. The continuum limit is then defined at fixed T′/L. Both cases have previously been investigated in the pure gauge theory. Here we define fermionic correlation functions and study their approach to the continuum limit at tree-level of perturbation theory.
