Tensor form factors of B -> K-1 transition from QCD light cone sum rules 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.
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.
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.
Pion-baryon coupling constants in light cone QCD sum rules Alıyev, Tahmasıb; Savcı, Mustafa (2000-01-01) We calculate the pi Sigma Lambda and pi Sigma Sigma coupling constants in light cone QCD sum rules for the structure sigma(alpha beta)gamma(5)p(alpha)q(beta). A comparison of our results on these coupling constants with the predictions of SU(6) symmetry is presented.
Radiative Delta -> N gamma decay in light cone QCD Alıyev, Tahmasıb; Savcı, Mustafa (1999-12-01) The g(Delta N gamma) coupling for the Delta-->N gamma decay is calculated in the framework of the light cone QCD sum rules and is found to be g(Delta N gamma)=(1.6+/-0.2) GeV-1. Using this value of g(Delta N gamma) we estimate the branching ratio of the Delta(+)-->N gamma decay, which is in a very good agreement with the experimental result. [S0556-2821(99)02023-8].
