The ground and first excited states of the decuplet baryons are studied using the two-point QCD sum rule approach. The mass and residue of these states are computed and compared with the existing experimental data and other theoretical predictions. The results for the masses of the ground state particles as well as the excited Delta and Sigma* states are in good consistency with experimental data. Our results on the excited Xi* and Omega(-) states reveal that the experimentally poorly known Xi(1950) and Omega(-) (2250) can be assigned to the first excited states in Xi* and Omega(-) channels, respectively.

Tensor form factors of B -> K-1 transition from QCD light cone sum rules Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-05-30) The tensor form factors of B into p-wave axial vector meson transition are calculated within light cone QCD sum rules method. The parametrizations of the tensor form factors based on the series expansion are presented.
Magnetic moments of decuplet baryons in light cone QCD Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2000-09-01) We calculate the magnetic moments of decuplet baryons containing strange quarks within the framework of light cone QCD sum rules taking into account the SU(3) flavor symmetry breaking effects. It is obtained that magnetic moments of the neutral Sigma(*0) and Xi(*0) baryons are mainly determined by the SU(3) breaking terms. A comparison of our results on the magnetic moments of the decuplet baryons with the predictions of other approaches is presented.
Heavy chi(Q) (2) tensor mesons in QCD Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2010-06-14) The masses and decay constants of the ground state heavy chi(Q2) (Q = b, c) tensor mesons are calculated in the framework of the QCD sum rules approach. The obtained results on the masses are in good consistency with the experimental values. Our predictions on the decay constants can be verified in the future experiments.
Unitary structure of the QCD sum rules and KYN and KY Xi couplings Aliev, T; Özpineci, Altuğ; Yakovlev, SB; Zamiralov, VS (2005-06-20) New relations between QCD Borel sum rules for strong coupling constants of K-mesons to baryons are derived. It is shown that starting from the sum rule for the coupling constants g(pi Sigma Sigma) and g(pi Sigma Lambda) it is straightforward to obtain corresponding sum rules for the g(KYN), G(KY Xi) couplings, Y = Sigma,Lambda.
Pseudospin and spin symmetry in the Dirac equation with Woods-Saxon potential and tensor potential AYDOĞDU, OKTAY; Sever, Ramazan (2010-01-01) The Dirac equation is solved approximately for the Woods-Saxon potential and a tensor potential with the arbitrary spin-orbit coupling quantum number kappa under pseudospin and spin symmetry. The energy eigenvalues and the Dirac spinors are obtained in terms of hypergeometric functions. The energy eigenvalues are calculated numerically.
