Meson Supermultiplet Decay Constants
We use a covariant supermultiplet theory to determine the primary coupling constant associated with several types of two-body meson decay. Despite the diverse range of decays considered the primary coupling constant is surprisingly uniform. We envisage the extension of the techniques to heavy quark cases, including as preliminary examples the calculation of the D * + and D * 0 total decay width...
متن کاملB Meson Decay Constants Using NRQCD
Recent results for B meson decay constants with NRQCD b-quarks and clover light quarks are discussed. Perturbative matching factors through O(α/M) are now available and incorporated into the analyses. An O(α a) improvement term to the heavy-light axial current is identified and included. The slope of fP S √ MP S versus 1/MP S is significantly reduced by these corrections.
متن کاملChiral Corrections to Vector Meson Decay Constants
We calculate the leading quark mass corrections of order mq log(mq), mq and m 3/2 q to the vector meson decay constants within Heavy Vector Meson Chiral Perturbation Theory. We discuss the issue of electromagnetic gauge invariance and the heavy mass expansion. Reasonably good fits to the observed decay constants are obtained.
متن کاملB Meson Decay Constants From NRQCD
We present quenched results for B meson decay constants using NRQCD b quarks and O(a) tadpole improved clover light quarks. For the first time, one-loop matching factors between lattice and continuum currents are incorporated through O(α/M) taking operator mixing fully into account. This includes an important O(α a) discretization correction to the heavy-light axial vector current. We find f B ...
متن کاملCharmed-meson decay constants in three-flavor lattice QCD.
We present the first lattice QCD calculation with realistic sea quark content of the D+-meson decay constant f(D+). We use the MILC Collaboration's publicly available ensembles of lattice gauge fields, which have a quark sea with two flavors (up and down) much lighter than a third (strange). We obtain f(D+)=201+/-3+/-17 MeV, where the errors are statistical and a combination of systematic error...
