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

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

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

Lattice QCD with dense heavy quarks

Autor: D. Toussaint, T. Blum, J. E. Hetrick

Publikováno v: Nuclear Physics B - Proceedings Supplements. 47:543-546

We study lattice QCD in the limit that the quark mass and chemical potential are simultaneously made large, resulting in a controllable density of quarks which do not move. This is similar in spirit to the quenched approximation for zero density QCD.
