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 and mixing parameters with physical light quark masses. We use MILC gluon field configurations that include , …
Locally-smeared operator product expansions
Christopher Monahan, Kostas Orginos
We propose a "locally-smeared Operator Product Expansion" (sOPE) to decompose non-local operators in terms of a basis of locally-smeared operators. The sOPE formally connects nonpe…
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…
form factors from lattice QCD
C. M. Bouchard, G. Peter Lepage, Christopher Monahan +2
We report the first lattice QCD calculation of the form factors for the standard model tree-level decay . In combination with future measurement, this calculation w…
