#### Magnetic moments of Xi '(Q)-Xi(Q) transitions in light cone QCD

(American Physical Society, 2014-03-11)

The Xi '(Q)-Xi(Q) transition magnetic moments are calculated in a framework of the light cone QCD sum rules method. The values of the transition magnetic moments obtained are compared with the predictions of the other ...

#### 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 ...

#### Mass and meson-current coupling constant of the tensor D-2*(2460)

(Springer, 2012-06)

We calculate the mass and meson-current coupling constant of the D-2*(2460) tensor meson in the framework of QCD sum rules. The obtained result on the mass is compatible with the experimental data.

#### 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 ...

#### Nucleon tensor form factors induced by isovector and isoscalar currents in QCD

(American Physical Society, 2011-10-11)

Using the most general form of the nucleon interpolating current, we calculate the tensor form factors of the nucleon within light cone QCD sum rules. A comparison of our results on tensor form factors with those of the ...

#### 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 coupling constants of heavy spin-3/2 baryons with light pseudoscalar mesons

(Elsevier, 2011-11)

The strong coupling constants among members of the heavy spin-3/2 baryons containing single heavy quark with light pseudoscalar mesons are calculated in the framework of the light cone QCD sum rules. Using symmetry arguments, ...

#### Vertices of the heavy spin-3/2 sextet baryons with light vector mesons in QCD

(Springer, 2011-10-21)

All transitions among the heavy spin-3/2 sextet baryons with participation of the light vector mesons (B(Q)(not equal)B(Q)V) are investigated in the framework of the light cone sum rules. These vertices are described by ...

#### Exclusive D-s -> (eta, eta ')l nu decays in light-cone QCD

(IOP Publishing, 2011-09)

Probing the (s) over bars content of the eta and eta' mesons and considering mixing between these states as well as gluonic contributions, the form factors responsible for semileptonic D-s -> (eta, eta')l nu transitions ...

#### 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 ...
