The decay constants for the strong off-shell B* --> B rho and D* --> D rho decays are calculated in the framework of light cone QCD sum rules. The results are shown to be in agreement with the predictions of the ''classical'' sum rules method, and with those of the vector dominance model.

Alıyev, Tahmasıb; Savcı, Mustafa (2000-04-01)
The strong coupling constants g(K Lambda N) and g(K Sigma N) for the structure sigma(mu nu)gamma(5) are calculated within light-cone QCD sum rules. A comparison of our results on these couplings with predictions from traditional QCD sum rules is presented.
Heavy chi(Q) (2) tensor mesons in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2010-06-14)
The masses and decay constants of the ground state heavy chi(Q2) (Q = b, c) tensor mesons are calculated in the framework of the QCD sum rules approach. The obtained results on the masses are in good consistency with the experimental values. Our predictions on the decay constants can be verified in the future experiments.
Light cone QCD sum rule analysis of B->Kl(+)l(-) decay
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (1997-05-08)
We calculate the transition formfactors for the B --> Kl(+)l(-) decay in the framework of the light cone QCD sum rules. The invariant dilepton mass distribution and the final lepton longitudinal polarization asymmetry are investigated. The comparison analysis of our results with traditional sum rules method predictions on the formfactors is performed. (C) 1997 Elsevier Science B.V.

Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-05-30)
The tensor form factors of B into p-wave axial vector meson transition are calculated within light cone QCD sum rules method. The parametrizations of the tensor form factors based on the series expansion are presented.
Vector meson dominance and radiative decays of heavy spin-3/2 baryons to heavy spin-1/2 baryons
Alıyev, Tahmasıb; Savcı, Mustafa (2012-04-10)
Using the calculated values of the strong coupling constants of the heavy sextet spin-3/2 baryons to sextet and antitriplet heavy spin-1/2 baryons with light vector mesons within the light cone QCD sum rules method, and vector meson dominance assumption, the radiative decay widths are calculated. These widths are compared with the "direct" radiative decay widths predicted in the framework of the light cone QCD sum rules.
