Are the new excited Omega(c) baryons negative parity states?

Aliev, T. M.
Bilmis, S.
Savcı, Mustafa
We calculate the mass and residue of the newly observed Omega(c) (3000) and Omega(c) (3066) states with quantum numbers J(P) = 1/2(-) and 3/2(-) within QCD sum rules. The calculation is carried out by using the general form for interpolating current for J = 1/2 baryon. Our predictions on masses are in good agreement with the experimental results.


Charged lepton flavor physics and extra dimensions
Iltan, E. I. (World Scientific Pub Co Pte Lt, 2007-06-28)
We estimate the charged lepton electric dipole moments and the branching ratios of radiative lepton flavor violating decays in the framework of the two Higgs doublet model with the inclusion of two extra dimensions. Here, we consider that the new Higgs doublet is accessible to one of the extra dimensions with a Gaussian profile and the fermions are accessible to the other extra dimension with uniform zero-mode profile. We observe that the numerical values of the physical quantities studied enhance with the ...
The Lorentz and CPT violating effects on H-o -> f(+)f(-) (ZZ, W+W-) decays
Iltan, EO (World Scientific Pub Co Pte Lt, 2004-02-10)
We study the Lorentz and CPT violating effects on the ratio BRLorVio/Br-SM where BRLorVio (BRSM) is the branching ratios coming from the Lorentz violating effects (the SM), for the decays H-0 --> f(+)f(-) (f = quarks and charged leptons) and H-0 --> ZZ(W+W-). We observe that these new effects are too small to be detected, especially for f(+)f(-) output, since the corresponding coefficients are highly suppressed at the low energy scale.

Axial form-factor of the radiative decay of charged pion is calculated using QCD sum rules method for non-diagonal correlator. For the ratio gamma = F(A)(0)/F(V)(0) we find gamma = 0.6 +/- 0.15.
The omega sigma gamma-vertex in light cone QCD sum rules
Gokalp, A; Yılmaz, Osman (IOP Publishing, 2002-06-01)
We investigate the omegasigmagamma-vertex and estimate the coupling constant g(omegasigmagamma) in the framework of the light cone QCD sum rules. We compare our result with the values of this coupling constant deduced from a phenomenological analysis of omega --> pipigamma decays.
B-c and heavy meson spectroscopy in the local approximation of the Schrodinger equation with relativistic kinematics
Ikhdair, SM; Sever, Ramazan (World Scientific Pub Co Pte Lt, 2005-07-10)
We present bound state masses of the self-conjugate and non-self-conjugate mesons in the context of the Schrodinger equation taking into account the relativistic kinematics and the quark spins. We apply the usual interaction by adding the spin dependent correction. The hyperfine splittings for the 2S charmonium and 1S bottomonium are calculated. The pseudoscalar and vector decay constants of the B-c meson and the unperturbed radial wave function at the origin are also calculated. We have obtained a local eq...
