Download or read book Decay Constants of B and D Mesons from Non-pertubatively Improved Lattice QCD. written by and published by . This book was released on 2000 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The decay constants of B and D mesons are computed in quenched lattice QCD at two different values of the coupling. The action and operators are? (a) improved with non-perturbative coefficients where available. The results and systematic errors are discussed in detail. Results for vector decay constants, flavour symmetry breaking ratios of decay constants, the pseudoscalar-vector mass splitting and D meson masses are also presented.
