Low energy constants from the MILC Collaboration

Autor: Bernard, C., DeTar, C., Gottlieb, Steven, Heller, U. M., Hetrick, J. E., Osborn, L. Levkova J., Renner, D., Sugar, R., Toussaint, D.

Based on ongoing simulations, we update our results for low energy constants, decay constants, and light quark masses. The simulations employ three dynamical flavors of improved staggered quarks.

Publikováno v: Journal of Physics: Conference Series. 16:160-164

By numerical study of the simple bound states of light quarks, in particular the π and K mesons, we are able to deduce fundamental quark properties. Using the "improved staggered" discretization of QCD, the MILC Collaboration has performed a series

Determination of |V(us)|| from a lattice QCD calculation of the K → πℓν semileptonic form factor with physical quark masses

Publikováno v: Physical review letters. 112(11)

We calculate the kaon semileptonic form factor f+(0) from lattice QCD, working, for the first time, at the physical light-quark masses. We use gauge configurations generated by the MILC Collaboration with Nf = 2 + 1 + 1 flavors of sea quarks, which i

A calculation of the ratio of leptonic decay constants ${f}_{{K}^{+}}/{f}_{{\ensuremath{\pi}}^{+}}$ makes possible a precise determination of the ratio of Cabibbo-Kobayashi-Maskawa (CKM) matrix elements $|{V}_{\mathrm{us}}|/|{V}_{\mathrm{ud}}|$ in th

Leptonic-decay-constant ratio f(K+)/f(π+) from lattice QCD with physical light quarks

Autor: A, Bazavov, C, Bernard, C, DeTar, J, Foley, W, Freeman, Steven, Gottlieb, U M, Heller, J E, Hetrick, J, Kim, J, Laiho, L, Levkova, M, Lightman, J, Osborn, S, Qiu, R L, Sugar, D, Toussaint, R S, Van de Water, R, Zhou

Publikováno v: Physical review letters. 110(17)

A calculation of the ratio of leptonic decay constants f(K+)/f(π+) makes possible a precise determination of the ratio of Cabibbo-Kobayashi-Maskawa (CKM) matrix elements |V(us)|/|V(ud)| in the standard model, and places a stringent constraint on the

We report results from full QCD calculations with two flavors of dynamical staggered fermions on anisotropic lattices. The physical anisotropy as determined from spatial and temporal masses, their corresponding dispersion relations, and spatial and t
