The form factors of gamma*N -> Delta (1600) transition is calculated within the light-cone sum rules assuming that Delta(+) (1600) is the first radial excitation of Delta(1232). The Q(2) dependence of the magnetic dipole (G) over tilde (M) (Q(2)), electric quadrupole (G) over tilde (E) (Q(2)), and Coulomb quadrupole (G) over tilde (c) (Q(2)) form factors are investigated. Moreover, the Q(2) dependence of the ratios R-EM = - (G) over tilde (E)(Q(2))/(G) over tilde (M)(Q(2)) and R-SM = -1/4m Delta(1600)(2) root 4m(Delta)(1600)(2) Q(2) + (m(Delta)((1600))(2)-Q(2)-m(N)(2) (2)(G) over tilde (c)(Q(2))/(G) over tilde (M)(Q(2)) are studied. Finally, our predictions on (G) over tilde (M)(Q(2)), (G) over tilde (E) (Q(2)), and (G) over tilde (C) (Q(2)) are compared with the results of other theoretical approaches.

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.
N*(1535) -> N transition form-factors due to the axial current
Alıyev, Tahmasıb; Simsek, K. (American Physical Society (APS), 2019-09-24)
The form-factors for the transition N* (1535) -> N induced by isovector and isoscalar axial currents within the framework of light cone QCD sum rules by using the most general form of the interpolating current are calculated. In numerical calculations, we use two sets of values of input parameters. It is observed that the Q(2) dependence of the form-factor G(A) can be described by the dipole form. Moreover, the form-factors G(p)((S)) are found to be highly sensitive to the variations in the auxiliary parame...
The g(B*B rho) and g(D*D rho) coupling constants in QCD
Alıyev, Tahmasıb; Iltan, E; Pak, NK (Springer Science and Business Media LLC, 1996-01-01)
The g(B*B rho) and g(D*D rho) coupling constants are calculated at the intermediate momentum transfer interval 0.5 GeV2 less than or equal to Q(2) less than or equal to 1.5 GeV2, in the context of QCD sum rules. Our predictions are in good agreement with those of the Vector Dominance Model.
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.
Form factors of D-s(+) -> phi(l)over-bar nu decay in QCD light cone sum rule
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (Springer Science and Business Media LLC, 2004-12-01)
We calculate the form factors V, A(1), A(2) and A(0) appearing in the D-s --> phi transition by the light cone QCD sum rule method. We compare our results on these form factors with the current experimental results and existing theoretical calculations.
