#### Investigation of the B-c -> chi(c2)l((nu)over bar)(-) transition via QCD sum rules

(Springer, 2013-11-13)

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 ...

#### 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 ...

#### Light cone QCD sum rules study of the semileptonic heavy Xi(Q) and Xi(Q)' transitions to Xi and Sigma baryons

(Springer, 2012-01-20)

The semileptonic decays of heavy spin-1/2, Xi(b(c)) and Xi(b(c))' baryons to the light spin-1/2, Xi and S baryons are investigated in the framework of light cone QCD sum rules. In particular, using the most general form ...

#### 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 ...

#### Semileptonic Lambda b,c to nucleon transitions in full QCD at light cone

(American Physical Society, 2009-11)

The tree-level semileptonic Lambda(b)-> pl nu and Lambda(c)-> nl nu transitions are investigated using the light cone QCD sum rules approach in full theory. The spin 1/2, Lambda(Q) baryon with Q=b or c, is considered by ...

#### FCNC transitions of Lambda(b,c) to nucleon in SM

(IOP Publishing, 2010-11)

We provide a comprehensive study of semileptonic flavor-changing neutral current transitions for Lambda(b) -> nl(+) l(-) and Lambda(c) -> pl(+) l(-) in the context of light cone QCD sum rules. Using the most general form ...

#### 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 ...

#### Strong σbNB and σcND coupling constants in QCD

(Elsevier, 2015-11-01)

We study the strong interactions among the heavy bottom spin-1/2 σb baryon, nucleon and B meson as well as the heavy charmed spin-1/2 σc baryon, nucleon and D meson in the context of QCD sum rules. We calculate the ...

#### Strong couplings of negative and positive parity nucleons to the heavy baryons and mesons

(American Physical Society, 2015-07-20)

The strong coupling form factors related to the strong vertices of the positive and negative parity nucleons with the heavy Lambda(b[c])[Sigma b[c]] baryons and heavy B*[D*] vector mesons are calculated using a threepoint ...
