#### Semileptonic transition of Sigma(b) to Sigma in light cone QCD sum rules

(American Physical Society, 2012-01-03)

We use distribution amplitudes of the light Sigma baryon and the most general form of the interpolating current for heavy Sigma(b) baryon to investigate the semileptonic Sigma(b) -> Sigma l(+)l(-) transition in light cone ...

#### Thermal properties of the heavy axial vector quarkonia

(Institute of Atomic Physics, 2014)

Using the additional operators coming up at finite temperature, we calculate the masses and decay constants of the P wave heavy axial-vector chi(b1) and chi(c1) quarkonia in the framework of thermal QCD sum rules. In the ...

#### 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

(Springer, 2014-10-21)

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 ...

#### Transition form factors of chi(b2)(1P) -> B-c(l)over-barv in QCD

(Hindawi, 2016)

The form factors of the semileptonic chi(b2)(1P) -> B-c(l) over barv decay are calculated by using the QCD sum rule technique. The results obtained are then used to estimate the decay widths of this transition in all lepton ...

#### On the nature of the newly discovered omega states

(EPL Association, 2017-06)

The mass and residue of the ground-state, as well as the first orbital and radial excitations of the heavy Omega(Q) baryons with Q being b or c quark, for both J = 1/2 and J = 3/2 are calculated by means of the QCD two-point ...

#### Decay widths of the excited Omega(b) baryons

(American Physical Society, 2017-11)

The LHCb Collaboration recently observed five narrow Omega(0)(c) resonances and measured their masses and widths through the decays Omega(0)(c) -> Xi(+)(c) K-. Motivated by this discovery, and also by the fact that the ...
