Different versions of improved staggered fermions can be used as valencequarks to reduce discretization effects in lattice QCD calculations whileincreasing statistics on existing staggered gauge ensembles. Such mixed-actionsimulations can be used to improve determinations of light quark masses,Gasser-Leutwyler couplings, decay constants, and other parameters relevant toparticle phenomenology. We recall the generalization of ordinary, unmixedstaggered chiral perturbation theory required to describe data from latticecalculations with a mixed action such as with HYP staggered valence quarks andasqtad sea quarks. We calculate the next-to-leading order loop diagramscontributing to the masses and decay constants of the flavored pseudo-Goldstonebosons of all tastes and here report results for the decay constants andvalence-valence masses.
