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.

Light cone QCD sum rules analysis of the axial N ->Delta transition form factors
Alıyev, Tahmasıb; Özpineci, Altuğ (Elsevier BV, 2008-02-01)
The axial N - Delta(1232) transition form factors are calculated within the light cone QCD sum rules method. A comparison of our results with the predictions of lattice theory and quark model is presented.
Radiative phi -> f(0)(980)gamma decay in light cone QCD sum rules
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2002-02-21)
The light cone QCD sum rules method is used to calculate the transition form factor for the radiative phi --> f(0gamma) decay, assuming that the quark content of the f(0) meson is pare (s) over bars state. The branching ratio is estimated to be beta(phi --> f(0)gamma) = 3.5 x (1 +/- 0.3) x 10(-4). A comparison of our prediction on branching ratio with the theoretical results and experimental data existing in literature 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.
g(B*B rho) and g(D*D rho) coupling constants in light cone QCD sum rules
Alıyev, Tahmasıb; Iltan, E; Pak, NK (1996-01-01)
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.
Rare B->K*l(+)l(-) decay in light cone QCD
Alıyev, Tahmasıb; Savcı, Mustafa; Özpineci, Altuğ (1997-10-01)
We investigate the transition form factors for the B-->K*l(+)l(-) (l = mu, tau) decay in light cone QCD. It is found that the light cone and three-point QCD sum rule analyses for some of the form factors for the decay B-->K*l(+)l(-) lead to absolutely different q(2) dependence. The invariant dilepton mass distributions for the B-->K*mu(+)mu(-) and B-->K*tau(+)tau(-) decays and final lepton longitudinal polarization asymmetry, which includes both short-and long-distance contributions, are also calculated.
