Decay Constant of Pseudoscalar Meson in the Heavy Mass Limit
نویسنده
چکیده
The leptonic decay constant of the pseudoscalar mesons a calculated by use of the relativistic constituent quark model constructed on the point form of Poincare-covariant quantum mechanics. We discuss the role relativistic corrections for decay constants of pseudoscalar mesons with heavy quarks. We consider the heavy mass limit of decay constant for two-particle system with equal masses.

Weak Decay Constant of Pseudoscalar Mesons in a QCD-Inspired Model
Effective theories applied to describe hadrons, which are inspired by Quantum Chromodynamics [1, 2, 3], can be useful in indicating direct correlations between different hadronic properties. In this way, it is possible to pin down the relevant dependence of the observables with some physical scales that otherwise would have no simple reason to show a direct relation, besides being properties of...
متن کاملFinite Mass Corrections to Leptonic Decay Constants in the Heavy Quark Effective Theory
We calculate finite mass corrections to leptonic decay constants in HQET using QCD sum rules. The results are given to two–loop accuracy including renormalization group analysis. The contribution of unknown two–loop anomalous dimension matrix–elements is estimated. We find that the 1/mQ corrections to fP , the decay constant of a pseudoscalar meson, amount −(23 ± 4 ± 2)% for the B meson. The fi...

We employ a Dyson-Schwinger equation model to effect a unified and uniformly accurate description of lightand heavy-meson observables, which we characterise by heavy-meson leptonic decays, semileptonic heavy-to-heavy and heavy-to-light transitions B → D∗, D, ρ, π; D → K∗, K, π, radiative and strong decays B∗ → Bγ; D∗ → Dγ, Dπ, and the rare B → K∗γ flavour-changing neutral-current process. We el...
متن کاملHadron Physics and the Dyson–Schwinger Equations of QCD
We use the Bethe–Salpeter equation in rainbow-ladder truncation to calculate the ground state mesons from the chiral limit to bottomonium, with an effective interaction that was previously fitted to the chiral condensate and pion decay constant. Our results are in reasonable agreement with the data, as are the vector and pseudoscalar decay constants. The meson mass differences tend to become co...
متن کاملHeavy-Light Mesons with Quenched Lattice NRQCD: Results on Decay Constants
We present a quenched lattice calculation of heavy-light meson decay constants, using non-relativistic (NRQCD) heavy quarks in the mass region of the b quark and heavier, and clover-improved light quarks. The NRQCD Hamiltonian and the heavy-light current include the corrections at first order in the expansion in the inverse heavy quark mass. We study the dependence of the decay constants on the...
