Electromagnetic structure and weak decay of pseudoscalar mesons in a light-front QCD-inspired model
نویسنده
چکیده
We study the scaling of the S1 −1 S0 meson mass splitting and the pseudoscalar weak decay constants with the mass of the meson, as seen in the available experimental data. We use an effective light-front QCD-inspired dynamical model regulated at short-distances to describe the valence component of the pseudoscalar mesons. The experimentally known values of the mass splittings, decay constants (from global lattice-QCD averages) and the pion charge form factor up to 4 [GeV/c]2 are reasonably described by the model.

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 کاملSemileptonic decay of a heavy-light pseudoscalar to a light vector meson
Semileptonic decays of heavy-light mesons are of interest because they can be used to determine elements of the CKM matrix. The nonperturbative QCD information needed to understand a decay can be calculated in lattice QCD. In the case of the decays D → K∗ and Ds → φ the branching ratios have been accurately measured and the relevant CKM matrix element (Vcs) is well determined by other methods [...
متن کاملWeak Form Factors for Heavy Meson Decays
We calculate the form factors for weak decays of B(s) and D(s) mesons to light pseudoscalar and vector mesons within a relativistic dispersion approach based on the constituent quark picture. This approach gives the form factors as relativistic double spectral representations in terms of the wave functions of the initial and final mesons. The form factors have the correct analytic properties an...
متن کاملTwo Photon Width of Heavy Pseudoscalar Mesons
In this work we revisit the calculation of the two photon width of ηc, highlighting newest experimental results and updating the potential model calculation. Unlike the ηc, the ηb state hasn’t been observed yet. We will examine various theoretical predictions for the electromagnetic decay of the lightest bb bound state. We start with the two photon decay width of a pseudoscalar quark– antiquark...
متن کاملImproved QCD Sum-Rule Approach to Heavy-Meson Decay Constants
A visible improvement of the QCD sum-rule framework, achieved only recently by a slightly more sophisticated consideration of the hadron excitations and continuum, is applied to the extraction of the decay constants of heavy-light pseudoscalar mesons, such as the D, Ds, B and Bs mesons, from two-point correlators of heavy-light pseudoscalar currents [1]. This analysis is carried out entirely in...
