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

RADIATIVE B(C)ASTERISK-]B(C)GAMMA DECAY IN QCD SUM-RULES Alıyev, Tahmasıb; PAK, NK (1994-06-09) The radiative decay B(c)* --> B(c)gamma is investigated in the framework of QCD sum rules, including power correction approximately [G2]. The transition amplitude and decay rates are estimated.
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 lepton flavor violating decays in the Randall-Sundrum background with localized leptons Iltan, E. O. (World Scientific Pub Co Pte Lt, 2008-03-20) We study the radiative lepton. avor violating l(i)-> l(j) gamma decays in the two- Higgs doublet model, respecting the Randall-Sundrum scenario and estimate the contributions of the KK modes of left- ( right-) handed charged lepton doublets ( singlets) on the branching ratios. We observe that the branching ratios are sensitive to the contributions of the charged lepton KK modes.
Exclusive radiative weak decays of B-c meson in light cone QCD Alıyev, Tahmasıb; Savcı, Mustafa (1998-12-01) We investigate the radiative B-c --> p(+)gamma and B-c --> K*(+gamma) decays in the standard model. The transition form factors are calculated in the framework of the light cone QCD sum rules method. We estimate the branching ratios of the B-c --> p(+)gamma and B-c --> K*(+)gamma decays.
Radiative decays of negative parity heavy baryons in the framework of the light cone QCD sum rules Agamaliev, A.K.; Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2017-2) The transition form factors responsible for the radiative Sigma(Q) -> Lambda(Q)gamma and Xi(')(Q) -> Xi(Q)gamma So decays of the negative parity baryons are examined within light cone QCD sum rules. The decay widths of the radiative transitions are calculated using the obtained results of the form factors. A comparison of our predictions on decay widths with the corresponding widths of positive parity baryons is given.
