Strong ΛbNB and ΛcND vertices
(American Physical Society, 2014-12-04)
We investigate the strong vertices among the Lambda(b), nucleon, and B meson as well as the Lambda(c), nucleon, and D meson in QCD. In particular, we calculate the strong coupling constants g Lambda bNB and g Lambda cND ...
Investigation of the D*s2(2573)+D+K0 vertex via QCD sum rules
(IOP Publishing, 2014-12-08)
In this work the D∗s2(2573)+D+K0 vertex is studied and the coupling constant corresponding to the D∗s2(2573)+ D+K0 transition is calculated. The calculation is performed using three point QCD sum rules method and the value ...
Strong D*(2)(2460)(0) -> D+pi(-) transition in QCD
(EDP Sciences, 2014-11-24)
This work presents the analysis of the transition D*(2)(2460)(0) > D+pi(-). In the calculation three point QCD sum rules method is applied and the value of the coupling constant for the considered vertex is obtained as ...
Analysis of the strong D-2* (2460)(0) -> D+ pi(-) and D-s2*(2573)(+) -> D+ K-0 transitions via QCD sum rules
The strong D-2* (2460)(0) -> D+ pi(-) and D-s2* (2573)(+) -> D+ K-0 transitions are analyzed via three-point QCD sum rules. First we calculate the corresponding strong coupling constants g(D2)*D pi and g(Ds2)*DK. Then we ...
