Electromagnetic form factors of octet baryons in QCD
The electromagnetic form factors of octet baryons are estimated within light cone QCD sum rules method, using the most general form of the interpolating current for baryons. A comparison of our predictions on the magnetic ...
Exploring the electromagnetic form factors of the scalar K-0(*)(1430), f(0)(1500) and a(0)(1450) mesons in light-cone sum rules
(American Physical Society, 2013-05-28)
We calculate the electromagnetic form factors of the scalar K-0(*)(1430), f(0)(1500) and a(0)(1450) mesons by considering them as regular quark-antiquark states and using their distribution amplitudes within the light-cone ...
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 ...
Investigation of the B-c -> chi(c2)l((nu)over bar)(-) transition via QCD sum rules
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 ...
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 ...
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.
Rare radiative Bc -> Ds1(2460)gamma transition in QCD
(American Physical Society, 2013-01-22)
We investigate the radiative B-c -> D-s1 gamma transition in the framework of QCD sum rules. In particular, we calculate the transition form factors responsible for this decay in both weak annihilation and electromagnetic ...
Masses and residues of the triply heavy spin-1/2 baryons
We calculate the masses and residues of the triply heavy spin-1/2 baryons using the most general form of their interpolating currents within the QCD sum rules method. We compare the obtained results with the existing ...
Semileptonic transition of Sigma(b) -> Sigma mu(+)mu(-) in the family non-universal Z ' model
(IOP Publishing, 2013-08)
Using newly available form factors obtained from light-cone QCD sum rules in full theory, we study the flavor-changing neutral current transition of Sigma(b) -> Sigma mu(+)mu(-) decay in the family non-universal Z' model. ...
Investigation of the D (s) (*) D-s eta ((')) and B (s) (*) B-s eta ((')) vertices via QCD sum rules
The strong-coupling constants among mesons are very important quantities as they can provide useful information on the nature of strong interaction among hadrons as well as the QCD vacuum. In this article, we investigate ...
