The form factors of the semileptonic B-c -> S(AV)l nu (l=tau, mu, e) transitions, where S and AV denote the scalar X-c0 and axial-vector (X-c1,h(c)) mesons, are calculated within the framework of the three-point QCD sum rules. The heavy quark effective theory limit of the form factors is also obtained and compared with the values of the original transition form factors. The results of form factors are used to estimate the total decay widths and branching ratios of these transitions. A comparison of our results on branching ratios with the predictions of other approaches is also presented.

Semileptonic B-c(-) -> D(*0)l nu transition in three-point QCD sum rules and heavy quark effective theory with gluon condensate corrections Ghahramany, N.; Khosravi, R.; Azizi, K. (American Physical Society (APS), 2008-12-01) Taking into account the gluon condensate contributions, the form factors of the semileptonic B-c(-) -> D(*0)l nu transition with l = tau, e are calculated in the framework of the three-point QCD sum rules. The heavy quark effective theory limit of the form factors is also computed. The relevant total decay width as well as the branching ratio are evaluated and compared with the predictions of the other nonperturbative approaches.
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.
Rare B -> l(+)l(-)gamma decay and new physics effects Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2001-11-08) Using the most general, model independent form of the effective Hamiltonian rare decays B --> l(+)l(-)gamma (l = mu, tau) are studied. The sensitivity of the photon energy distribution and branching ratio to the new Wilson coefficients is investigated.
Radiative Omega(Q)* -> Omega(Q)gamma and Xi(Q)* -> Xi(Q)'gamma transitions in light cone QCD Alıyev, Tahmasıb; SUNDU PAMUK, HAYRİYE (2015-01-14) We calculate the magnetic dipole and electric quadrupole moments associated with the radiative Omega(Q)* -> Omega(Q)gamma and Xi(Q)* -> Xi(Q)'gamma transitions with Q = b or c in the framework of light cone QCD sum rules. It is found that the corresponding quadrupole moments are negligibly small, while the magnetic dipole moments are considerably large. A comparison of the results of the considered multi-pole moments as well as corresponding decay widths with the predictions of the vector dominance model is...
Semileptonic B-q -> D-q*l nu (q=s,d,u) decays in QCD sum rules Azizi, K.; Bayar, M. (American Physical Society (APS), 2008-09-01) The form factors relevant to B-q -> D-q*(J(P) = 1(-))l nu (q = s, d, u) decays are calculated in the framework of the three point QCD sum rules approach. The heavy quark effective theory prediction of the form factors as well as 1/m(b) corrections to those form factors are obtained. A comparison of the results for the ratio of form factors at zero recoil limit and other values of q(2) with the predictions of the subleading Isgur-Wise form factor application for B -> D*l nu is presented. The total decay widt...
