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.

Sigma(Q)Lambda(Q) transition magnetic moments in light cone QCD sum rules
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2002-05-01)
Using the general form of Sigma(Q) and Lambda(Q) (Q=b or c) currents, Sigma(Q)Lambda(Q) transition magnetic moments are calculated in the framework of the light cone QCD sum rules method. In this approach nonperturbative effects are described by the photon wave functions and only two-particle photon wave functions are taken into account. Our predictions of the transition magnetic moments are mu(Sigmac)Lambda(c)=-(1.5+/-0.4)mu(N) and mu(Sigmab)Lambda(b)=-(1.6+/-0.4)mu(N). A comparison of our results with the...
Magnetic moments of Delta baryons in light cone QCD sum rules
Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (2000-10-23)
We calculate the magnetic moments of Delta baryons within the framework of QCD sum rules. A comparison of our results on the magnetic moments of the Delta baryons with the predictions of different approaches is presented.
Scalar sigma meson effects in radiative rho(0)-meson decays
Gokalp, A; Solmaz, S; Yılmaz, Osman (2003-04-01)
We study the radiative rho(0)-->pi(+)pi(-)gamma and rho(0)-->pi(0)pi(0)gamma decays and we calculate their branching ratios using a phenomenological approach by adding to the amplitude calculated within the framework of chiral perturbation theory and vector meson dominance the amplitude of sigma-meson intermediate state. Our results for the branching ratios are in good agreement with the experimental values.
MUTUAL COUPLING EFFECTS OF FINITE RECTANGULAR PHASED-ARRAYS
YAVUZ, H; BUYUKDURA, OM (1994-04-14)
A rigorous integral equation formulation for the analysis of a phased array of flangemounted waveguide apertures is given for a finite number of elements and nonuniform spacings. The resulting set of ihtegrd equations is reduced to a matrix equation called the coupling matrix which relates the coefficients of all the modes in all the waveguides to one another. The solution then yields the dominant mode reflection coefficient, coefficients of scattered modes and hence the field in each waveguide. The blockTo...
Magnetic Moments of 70-Plet Baryons in Quark Model and QCD Sum Rules
Alıyev, Tahmasıb (2015-01-01)
Magnetic moments of the positive parity 70-plet baryons are estimated in the framework of the nonrelativistic quark model and QCD sum rules method. It is found that the magnetic moments of the 70-plet baryons can be expressed in terms of the F and D couplings and exhibit unitary symmetry. The QCD sum rules for the magnetic moments of the 70-plet octet baryons are formulated. A comparison of our results on magnetic moments of 56-plet and 70-plet baryons predicted from QCD sum rules is presented.
