Systematic Errors of Transition Form Factors Extracted by Means of Light-cone Sum Rules
This talk presents results of our study of heavy-to-light transition form factors extracted with the help of light-cone sum rules. We employ a model with scalar particles interacting via massless-boson exchange and study the heavy-to-light correlator, relevant for the extraction of the transition form factor. We calculate this correlator in two different ways: by making use of the Bethe–Salpete...
متن کاملElectromagnetic form factors of the ρ meson in light cone QCD sum rules
We investigate the electromagnetic form factors of the ρ meson in light cone QCD sum rules. We find that the ratio of the magnetic and charge form factors is larger than two at all values of Q2, (Q2 ≥ 0.5 GeV 2). The values of the individual form factors at fixed values of Q2 predicted by the light cone QCD sum rules are quite different compared to the results of other approaches. These results...
متن کاملDlν̃ form factors in Light - Cone Sum Rules and the D - meson distribution amplitude
In this paper we calculate the weak form factors of the decays Bc(B) → Dlν̃ by using the chiral current correlator within the framework of the QCD light-cone sum rules (LCSR). The expressions of the form factors only depend on the leading twist distribution amplitude (DA) of the D meson. Three models of the D-meson distribution amplitude are employed and the calculated form factor FBc→D(0) is gi...
متن کامل, φ Decay Form Factors from Light - Cone Sum Rules Revisited
We present an improved calculation of B → light vector form factors from light-cone sum rules, including one-loop radiative corrections to twist-2 and twist-3 contributions, and leading order twist-4 corrections. The total theoretical uncertainty of our results at zero momentum transfer is typically 10% and can be improved, at least in part, by reducing the uncertainty of hadronic input paramet...
متن کاملPhoton-meson transition form factors of light pseudoscalar mesons
The photon-meson transition form factors of light pseudoscalar mesons π0, η, and η′ are systematically calculated in a light-cone framework, which is applicable as a light-cone quark model at low Q2 and is also physically in accordance with the light-cone pQCD approach at large Q2. The calculated results agree with the available experimental data at high energy scale. We also predict the low Q2...
