Investigation of the semileptonic transition of the B into the orbitally excited charmed tensor meson
(American Physical Society, 2013-08-09)
The transition form factors of the semileptonic B -> D-2*(2460)l (nu) over bar (l = tau, mu, e) decay channel are calculated within the framework of the three- point QCD sum rules. The fit functions of the form factors are ...
Investigation of the B-c -> chi(c2)l((nu)over bar)(-) transition via QCD sum rules
We calculate the transition form factors of the semileptonic in the framework of QCD sum rules taking into account the two-gluon condensate corrections. Using the obtained results of form factors we estimate the decay ...
Properties of Ds2*(2573) charmed-strange tensor meson
(American Physical Society, 2013-08-19)
The mass and current coupling constant of the D-s2*(2573) charmed-strange meson is calculated in the framework of the two-point QCD sum rule approach. Although the quantum numbers of this meson are not exactly known, its ...
Investigation of the D (s) (*) D-s eta ((')) and B (s) (*) B-s eta ((')) vertices via QCD sum rules
The strong-coupling constants among mesons are very important quantities as they can provide useful information on the nature of strong interaction among hadrons as well as the QCD vacuum. In this article, we investigate ...
Properties of D - 2 * (2460) tensor meson and semileptonic transition of B -> D - 2 * (2460) l(v)over - bar
We employ QCD sum rules to calculate the leptonic decay constant of the D-2*(2460) tensor meson and the transition form factors of the semileptonic B -> D-2*(2460)l (v) over bar (l = tau,mu,e) decay channel. Using the fit ...
Analysis of the semileptonic transition of heavy Xi(Q) baryon to Xi baryon in Light Cone QCD Sum Rules
This study presents the analysis of form factor calculations of semileptonic transitions of heavy baryons via light cone QCD sum rules. The work covers the semileptonic transitions of the Xi(b) and Xi(c) baryons. The form ...
