We analyze the semileptonic D-q -> K-1 center dot nu transition with q=u, d, s, in the framework of the three-point QCD sum rules and the nonleptonic D -> K-1 pi decay within the QCD factorization approach. We study D-q to K-1(1270) and K-1(1400) transition form factors by separating the mixture of the K-1(1270) and K-1(1400) states. Using the transition form factors of the D -> K-1, we analyze the nonleptonic D -> K-1 pi decay. We also present the decay amplitude and decay width of these decays in terms of the transition form factors. The branching ratios of these channel modes are also calculated at different values of the mixing angle theta(K1) and compared with the existing experimental data for the nonleptonic case.

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...
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.
Dualisation of the general scalar coset in supergravity theories Yilmaz, NT (Elsevier BV, 2003-08-04) The dualised formulation of the symmetric space sigma model is peformed for a general scalar coset G/K where G is a maximally non-compact group and K is it's maximal compact subgroup. By using the twisted self-duality condition the general form of the first-order equations are obtained. The results are applied to the example of SL(2, R)/SO(2) scalar manifold of the IIB supergravity.
Dualisation of the Salam-Sugin D-8 supergravity Dereli, T; Yilmaz, NT (Elsevier BV, 2004-07-19) The first-order formulation of the Salam-Sezgin D = 8 supergravity coupled to N vector multiplets is discussed. The non-linear realization of the bosonic sector of the D = 8 matter coupled Salam-Sezgin supergravity is introduced by the dualisation of the fields and by constructing the Lie superalgebra of the symmetry group of the doubled field strength.

Excited heavy masons decay form factors in light cone QCD Alıyev, Tahmasıb; Savcı, Mustafa; Özpineci, Altuğ (Elsevier BV, 1998-03-12) The form factors of B-1 --> pi and D-1 --> pi transitions, where B-1(D-1) is the 1(+) P-wave <(Q)over bar gamma(nu)gamma(5)q> meson state, are calculated in the framework of the light cone QCD. Furthermore, these form factors are compared with the pole dominance model prediction using the values of the strong coupling constants g(B1B*pi) and g(D1D*pi), and a good agreement between these two different descriptions is observed.
