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 ...
The masses and residues of doubly heavy spin-3/2 baryons
(IOP Publishing, 2013-06)
The masses and residues of the spin-3/2 doubly heavy baryons are calculated within the QCD sum rules method. A comparison of our predictions with those existing in the literature is also made.
On the mass and decay constant of K-2*(1430) tensor meson
(IOP Publishing, 2010-02)
The mass and decay constant of the ground state strange tensor meson K-2* (1430) with I(J(P)) = 1/2(2(+)) are calculated using the QCD sum rules method. The results are consistent with the experimental data. It is found ...
Strong coupling constants of decuplet baryons with vector mesons
(American Physical Society, 2010-11-10)
We provide a comprehensive study of strong coupling constants of decuplet baryons with light nonet vector mesons in the framework of light cone QCD sum rules. Using the symmetry arguments, we argue that all coupling constants ...
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 P-wave scalar and S-wave pseudo-scalar charmonia semileptonic transitions to the D-s(D) meson in QCD
(IOP Publishing, 2010-07)
In this work, the semileptonic decays of the scalar charmonium state X-c0 and the pseudo scalar charmonia states eta(c)(1s) and eta(c)(2s) into D-s and D mesons are analyzed. The form factors of the transitions X-c0 -> ...
Magnetic dipole moment of the light tensor mesons in light cone QCD sum rules
(IOP Publishing, 2010-07)
The magnetic dipole moments of the light tensor mesons f(2), a(2) and the strange K-2*(0)(1430) tensor meson are calculated in the framework of the light cone QCD sum rules. It is observed that the values of the magnetic ...
Properties of doubly and triply heavy baryons
(IOP Publishing, 2014)
We calculate the mass and residue of the doubly/triply heavy spin-1/2 and spin-3/2 baryons containing two/three heavy b or c quarks in the framework of QCD sum rules. We use the most general interpolating currents in ...
Radiative transition of negative to positive parity nucleon
(American Physical Society, 2015-05-27)
We investigate the N*(1535) -> N gamma transition in the framework of light cone QCD sum rules. In particular, using the most general form of the interpolating current for the nucleon as well as the distribution amplitudes ...
Radial excitations of the decuplet baryons
The ground and first excited states of the decuplet baryons are studied using the two-point QCD sum rule approach. The mass and residue of these states are computed and compared with the existing experimental data and other ...
