We investigate the a(0)pieta-vertex in the framework of light-cone QCD sum rules. We estimate the coupling constant g(a0pieta) which is an essential ingredient in the analysis of physical processes involving a(0)(980) meson. We determine the decay width of the a(0) --> pi(0)eta decay and compare our result with experimental value.

The non-split scalar coset in supergravity theories Yilmaz, NT (Elsevier BV, 2003-12-22) The general non-split scalar coset of supergravity theories is discussed. The symmetric space sigma model is studied in two equivalent formulations and for different coset parametrizations. The dualisation and the local first order formulation is performed for the non-split scalar coset G/K when the rigid symmetry group G is a real form of a non-compact semisimple Lie group (not necessarily split) and the local symmetry group K is G's maximal compact subgroup. A comparison with the scalar cosets arising in ...
The neutralino mass: Correlation with the charginos Boz, Muge; Pak, Namik K. (World Scientific Pub Co Pte Lt, 2006-06-28) As the fundamental SU(2) supersymmetric parameters can be determined in the chargino sector, and the remaining fundamental parameters of the minimal supersymmetric extensions of the standard model can be analyzed in the neutralino sector, the two sectors can be correlated via these parameters. We have shown that for the CP-conserving case, the masses of all the neutralinos can be determined in terms of the chargino masses and tan beta. In this case the neutralinc, masses are quite insensitive to the variati...
The masses and residues of doubly heavy spin-3/2 baryons Alıyev, Tahmasıb; Savcı, Mustafa (IOP Publishing, 2013-06-01) The masses and residues of the spin-3/2 doubly heavy baryons are calculated within the QCD sum rules method. A comparison of our predictions with those existing in the literature is also made.
Properties of triply heavy spin-3/2 baryons Alıyev, Tahmasıb; Savcı, Mustafa (IOP Publishing, 2014-06-01) The masses and residues of the triply heavy spin-3/2 baryons are calculated in framework of the QCD sum rule approach. The obtained results are compared with the existing theoretical predictions in the literature.
Analysis of the rare Bc -> Ds,d*l(+)l(-) decays in QCD Azizi, K.; Falahati, F.; BASHIRY, VALİ; Zebarjad, S. M. (American Physical Society (APS), 2008-06-01) The rare B-c -> D(s,d)(*)l(+)l(-) decays are investigated in the framework of the three-point QCD sum rules approach. Considering the gluon condensate corrections to the correlation function, the form factors relevant to these transitions are calculated. The total decay width and branching ratio for these decays are also evaluated. The results for the branching ratios are in good agreement with the quark models.
