One-loop matching of Delta S=2 four-quark operators with improved staggered fermions
Thomas Becher, Elvira Gamiz, Kirill Melnikov
We compute O(alpha_s) lattice-to-continuum perturbative matching coefficients for the Delta S=2 flavor changing four-quark operators for the Asqtad improved staggered action. In co…

The self-energy of improved staggered quarks
Thomas Becher, Kirill Melnikov
We calculate the fermion self-energy at O(alpha_s) for the Symanzik improved staggered fermion action used in recent lattice simulations by the MILC collaboration. We demonstrate t…
