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.

Strong Coupling Constants of Heavy Baryons With Light Mesons in QCD Alıyev, Tahmasıb; Savcı, Mustafa (2012-06-21) The strong coupling constants of the heavy spin-1/2 and spin-3/2 baryons with light pseudoscalar and vector mesons are calculated in the framework of the light cone QCD sum rules. Using the symmetry arguments, some structure independent relations among different correlation functions are obtained. It is shown that all possible transitions are described by only one invariant function, whose explicit expression is structure dependent.
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.
Baryon-Baryon-Meson Coupling Constants in QCD Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2010-06-23) The strong coupling constant of decuplet and octet baryons to vector and pseudoscalar mesons are calculated in light cone QCD sum rules in general case and when the SU(3)(f) symmetry is taken into account. A comparison of the obtained results with the existing experimental data and predictions of the other nonperturbative approaches is also made.
Strong coupling constants of the octet baryons to Kand pi mesons in light cone QCD sum rules Alıyev, Tahmasıb; Özpineci, Altuğ (2007-06-20) In this work, the strong coupling constants of the octet baryons to the K and pi mesons are studied within the Light Cone QCD sum rule method. It is well known that in the SU(3)(f) limit, these couplings can be expressed in terms of only 2 constants, so called F and D constants. In this work, the SU(3)(f) symmetry violating effects are also studied and it is shown that all the coupling constants can be expressed in terms of four analytical functions of the quark parameters.
Strong coupling constants of heavy spin-3/2 baryons with light pseudoscalar mesons Alıyev, Tahmasıb; Savcı, Mustafa (2011-11-01) The strong coupling constants among members of the heavy spin-3/2 baryons containing single heavy quark with light pseudoscalar mesons are calculated in the framework of the light cone QCD sum rules. Using symmetry arguments, some structure independent relations among different correlation functions are obtained. It is shown that all possible transitions can be described in terms of one universal invariant function whose explicit expression is Lorenz structure dependent.
