The radiative decays B*(D*)-->B(D)gamma are investigated in the framework of light-cone QCD sum rules. The transition amplitude and decay rates are estimated. It is shown that our results for the branching ratios of D meson decays are in good agreement with the existing experimental data.

Radiative decays of decuplet to octet baryons in light cone QCD Alıyev, Tahmasıb; Özpineci, Altuğ (Elsevier BV, 2006-01-02) The radiative decays of decuplet to octet baryons are analyzed within the light cone QCD sum rules framework. The electromagnetic transition form factors for these decays are calculated at q(2) = 0 up to twist-4 accuracy for photon wave functions and including first order strange quark mass corrections. A comparison of our results with predictions of lattice theory and existing experimental data is presented. (c) 2005 Published by Elsevier B.V.
Radiative B-* meson decays in QCD sum rules Alıyev, Tahmasıb; Pak, NK (Springer Science and Business Media LLC, 1997-01-01) The decay constant g(B)* of the B* mesons and the transition amplitudes of the radiative decays B-a* --> B-a gamma are calculated in the frame-work of QCD sum rules. It is shown that the decay rates B* --> B gamma are one order smaller than the corresponding D* meson decays.
Radiative decays of the heavy tensor mesons in light cone QCD sum rules Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2019-01-11) The transition form factors of the radiative decays of the heavy tensor mesons to heavy pseudoscalar and heavy vector mesons are calculated in the framework of the light-cone QCD sum rules method at the point Q(2) = 0. Using the obtained values of the transition form factors at the point Q(2) = 0, the corresponding decay widths are estimated. The results show that the radiative decays of the heavy-light tensor mesons could potentially be measured in the future planned experiments at LHCb.
Semileptonic B -> a(1)l nu decay in QCD Alıyev, Tahmasıb; Savcı, Mustafa (1999-06-10) The form factors and the branching ratio of the B --> a(1)lv decay are calculated in framework of QCD sum rules. A comparison of our results on form factors and branching ratio with the results from constituent quark model is presented. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
Radiative decays of the p-wave charmed heavy baryons Alıyev, Tahmasıb; Savcı, Mustafa (Springer Science and Business Media LLC, 2019-05-23) The radiative decays of the p-wave charmed heavy baryons to the ground state baryon states are studied in the framework of the light cone QCD sum rules method. Firstly, the transition form factors that describe these transitions are estimated and then, using these form factors, the corresponding decay widths are calculated. A comparison of our results for the decay widths with those predicted by the other approaches existing in the literature is performed.
