| Abstract | We present a preliminary calculation of BK using domain-wall valence quarks and 2+1 flavors of improved staggered sea quarks. Both the size of the residu al quark mass, which measures the amount of chiral symmetry breaking, and of the mixed meso n splitting ∆mix, a measure of taste-symmetry breaking, show that discretization effect s are under control in our mixed action lattice simulations. We show preliminary data for pseudosc alar meson masses, decay constants andBK . We discuss general issues associated with the chiral extra polation of lattice data, and, as an example, present a preliminary chiral and continuum extr apolation of fπ . The quality of our data shows that the good chiral properties of domain-wall qu arks, in combination with the light sea quark masses and multiple lattice spacings available wi th the MILC staggered configurations, will allow for a precise determination of BK . |
