Beyond the Standard Model B-parameters with improved staggered fermions in QCD
We calculate the kaon mixing B-parameters for operators arising generically
in theories of physics beyond the standard model. We use HYP-smeared improved
staggered fermions on the MILC asqtad lattices. Operator matching
is done perturbatively at one-loop order. Chiral extrapolations are done using
"golden combinations" in which one-loop chiral logarithms are absent. For the
combined sea-quark mass and continuum extrapolation, we use three lattice
spacings: and . Our results have a
total error of 5-6%, which is dominated by the systematic error from matching
and continuum extrapolation. For two of the BSM -parameters, we agree with
results obtained using domain-wall and twisted-mass dynamical fermions, but we
disagree by for the other two.Comment: 7 pages, 5 figures, Lattice 2013 Proceedin
