Vector decay constants in quarkonia
Lattice NRQCD with leading finite lattice spacing errors removed is used to simulate heavy-heavy vector decay constants. Quenched simulations are performed at three values of the coupling and fifteen values of the quark mass. The improved gauge action with plaquettes and rectangles is used. Landau link improvement is used throughout. “Perturbative” and nonperturbative meson masses are compared....
متن کاملScaling behaviour of leptonic decay constants for heavy quarkonia and heavy mesons
In the framework of QCD sum rules one uses a scheme, allowing one to apply the conditions of both nonrelativistic heavy quark motion inside mesons and independence of nonsplitting nS-state density on the heavy quark flavours. In the leading order an analitic expression is derived for leptonic constants of both heavy quarkonia and heavy mesons with a single heavy quark. The expression allows one...
متن کاملDecay constants of P- and D-wave heavy-light mesons.
We investigate decay constants of P and D-wave heavy-light mesons within the mock-meson approach. Numerical estimates are obtained using the relativistic quark model. We also comment on recent calculations of heavy-light pseudo-scalar and vector decay constants. Typeset using REVTEX
متن کاملDecay Constants fD ∗ s
We calculate the decay constant of Ds and D ∗ s with B̄ 0 → D+l−ν and B̄0 → D+D s decays. In our analysis we assume the factorization ansatz and use two different form factor behaviours (constant and monopole-type) for F0(q 2). We also consider the QCDpenguin contributions in hadronic decays within the NDR renormalization scheme in a NLO calculation. We estimate the decay constant of the Ds meson...
متن کاملQuenched heavy-light decay constants.
We present results for heavy-light decay constants, using both propagating quarks and the static approximation, inO(a)-improved, quenched lattice QCD. At β = 6.2 on a 243×48 lattice we find fD = 185 + 4 − 3 (stat) + 42 − 7 (syst) MeV, fB = 160 + 6 − 6 + 53 − 19 MeV, fDs/fD = 1.18 + 2 − 2 and fBs/fB = 1.22 + 4 − 3 , in good agreement with earlier studies. From the static theory we obtain f stat ...
