Thermodynamics with 3 and 2+1 Flavors of Improved Staggered Quarks
C. Bernard, T. Burch, S. Datta +7
We present preliminary results from exploring the phase diagram of finite temperature QCD with three degenerate flavors and with two light flavors and the mass of the third held ap…
Assorted weak matrix elements involving the bottom quark
C. Bernard, T. Blum, T. DeGrand +9
As part of a larger project to estimate the fB decay constant, we are recalculating fB_static using a variational smearing method in an effort to improve accuracy. Preliminary resu…
Results for light pseudoscalars from three-flavor simulations
MILC Collaboration, C. Aubin, C. Bernard +8
We compute pseudoscalar meson masses and decay constants in partially quenched QCD with three dynamical flavors of improved staggered quarks. Fitting the lattice data to staggered…
Refining new-physics searches in B -> D tau nu decay with lattice QCD
Jon A. Bailey, A. Bazavov, C. Bernard +23
The semileptonic decay channel B -> D tau nu is sensitive to the presence of a scalar current, such as that mediated by a charged-Higgs boson. Recently the BaBar experiment reporte…
Improving HISQ propagator solves using deflation
Leon Hostetler, M. A. Clark, Carleton DeTar +2
Typically, the conjugate gradient (CG) algorithm employs mixed precision and even-odd preconditioning to compute propagators for highly improved staggered quarks (HISQ). This appro…
Topological susceptibility with the asqtad action
MILC collaboration, A. Bazavov, C. Bernard +12
Chiral perturbation theory predicts that in quantum chromodynamics (QCD), light dynamical quarks suppress the gauge-field topological susceptibility of the vacuum. The degree of su…
