B-meson mixing from full lattice QCD with physical u, d, s and c quarks

R. J. Dowdall, C. T. H. Davies, R. R. Horgan +3

We present the first lattice QCD calculation of the $B_{s}$ and $B_{d}$ mixing parameters with physical light quark masses. We use MILC gluon field configurations that include $u$ , $d$ …

Matching lattice and continuum four-fermion operators with nonrelativistic QCD and highly improved staggered quarks

Christopher Monahan, Elvira Gamiz, Ron Horgan +1

We match continuum and lattice heavy-light four-fermion operators at one loop in perturbation theory. For the heavy quarks we use nonrelativistic QCD and for the massless light qua…
