Next-to-Leading-Order Staggered Chiral Perturbation Theory

Abstract
We have extended staggered chiral perturbation theory to O(a^2 p^2), O(a^4), and O(a^2 m), the orders necessary for a full next-to-leading order calculation of pseudo-Goldstone boson masses and decay constants including taste-symmetry violations. We present predictions relating SO(4) taste-breaking splittings in masses, pseudoscalar decay constants, and dispersion relations. These can be used to test the fourth-root trick.
