The form factors of the semileptonic Bq -> D-q (J(P) = 0(-))lv with q =s, u,d transitions are calculated in the framework of three point QCD sum rules. Using the q(2) dependencies of the relevant form factors, the total decay width and the branching ratio for these decays are also evaluated. A comparison of our results for the form factors of B -> Dlv with the lattice QCD predictions within heavy quark effective theory and zero recoil limit is presented. Our results of the branching ratio are in good agreement with the constituent quark meson model for (q = s, u, d) and experiment for (q = u, d). The result of branching ratio for B-s -> D-s(1968)lv indicates that this transition can also be detected at LHC in the near future.

Tensor form factors of the octet hyperons in QCD
Küçükarslan, Ayşe; Özdem, Ulaş; Özpineci, Altuğ (American Physical Society (APS), 2016-11-11)
Light-cone QCD sum rules to leading order in QCD are used to investigate the tensor form factors of the Sigma-Sigma,Xi-Xi, and Sigma-Lambda transitions in the range 1 GeV2 <= Q(2) <= 10 GeV2. The DAs of Sigma,Xi, and. baryon have been calculated without higher-order terms. Then, studies including higher-order corrections have been done for the Sigma and. baryon Lambda The resulting form factors are obtained using these two DAs. We make a comparison with the predictions of the chiral quark soliton model.
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...

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.
Isovector axial vector form factors of octet-decuplet hyperon transition in QCD
KÜÇÜKARSLAN, AYŞE; Ozdem, U.; Özpineci, Altuğ (2015-01-01)
We calculate the isovector axial vector form factors of the octet-decuplet hyperon transitions within the framework of the light-cone QCD sum rules to leading in QCD and including higher-twist corrections. In particular, we motivate the most recent version of the Sigma and Lambda baryons distribution amplitudes, which are examined up to twist-6 based on conformal symmetry of the massless QCD Lagrangian.
gamma*N -> N(1535) transition form factors in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (2013-09-24)
The form factors, as well as the helicity amplitudes for the gamma*Nu -> Nu(1535) transition, are calculated in the framework of the QCD light-cone sum rules. The contamination coming from diagonal transition is eliminated by considering combinations of the sum rules corresponding to different Lorentz structures. A similar procedure is applied for the determination of the residue and mass of the negative-parity baryon. A comparison of our predictions on the helicity amplitudes with the existing theoretical ...
