Both non-zero and zero twisted mass values are considered. The results, including also data from simulations using the Wilson plaquette gauge action, are compared to next-to-leading order chiral perturbation theory formulas.53 pages, 11 tables, 18 figures; discussion extendedHigh Energy Physics - Latticetext
