Mass Formulas for Xi(c) and Xi(b) Baryons

The importance of taking into account the mixing of the heavy cascade baryons Xi and Xi' that have new quantum numbers in analyzing their properties is shown. The Ono quark model is considered by way of example. The masses of the new baryons and the Xi-Xi' mixing angles are obtained. The same approach is applied to the interpolating currents of these baryons within QCD sum rules.


Bound energy masses of mesons containing the fourth generation and iso-singlet quarks
Ikhdair, Sameer M.; Sever, Ramazan (World Scientific Pub Co Pte Lt, 2006-04-20)
The fourth Standard Model (SM) family quarks and weak iso-singlet quarks predicted by E-6 GUT are considered. The spin-average of the pseudoscalar eta(4)(n(1)S(0)) and vector psi(4)(n(3)S(1)) quarkonium binding masses of the new mesons formed by the fourth Standard Model (SM) family and iso-singlet E-6 with their mixings to ordinary quarks are investigated. Further, the fine and hyperfine mass splittings of the these states are also calculated. We solved the Schrodinger equation with logarithmic-and Martin ...
Mass spectra of heavy quarkonia and B-c decay constant for static scalar-vector interactions with relativistic kinematics
Ikhdair, SM; Sever, Ramazan (World Scientific Pub Co Pte Lt, 2005-11-10)
We reproduce masses of the self-conjugate and non-self-conjugate mesons in the context of the spinless Salpeter equation taking into account the relativistic kinematics and the quark spins. The hyperfine splittings for the 2S charmonium and IS bottomonium are also calculated. Further, the pseudoscalar and vector decay constants of the Be meson and the unperturbed radial wave function at the origin are also calculated. We have obtained a local equation with a complete relativistic corrections to a class of t...
Masses and residues of the triply heavy spin-1/2 baryons
Alıyev, Tahmasıb; Savcı, Mustafa (Springer Science and Business Media LLC, 2013-04-01)
We calculate the masses and residues of the triply heavy spin-1/2 baryons using the most general form of their interpolating currents within the QCD sum rules method. We compare the obtained results with the existing theoretical predictions in the literature.
QCD sum rules for the coupling constants g(KYN) and g(KY Xi)
Aliev, T.; Zamiralov, V. S.; Lepshokov, S. N.; Özpineci, Altuğ; Yakovlev, S. B. (Pleiades Publishing Ltd, 2007-05-01)
New relations between Borel QCD sum rules for the strong couplings of baryons to kaons are derived. It is shown that, on the basis of the sum rules for the coupling constants g(pi Sigma Sigma) and g(pi Sigma Lambda), the corresponding sum rules can be directly obtained for the coupling constants g(KYN) and g(KY Xi), Y = Sigma, Lambda. The values of these coupling constants are calculated in the fiducial interval 1.0 <= M-2 <= 1.4 GeV2 at t = -1.
Heavy baryon-light vector meson couplings in QCD
Alıyev, Tahmasıb; Savcı, Mustafa (Elsevier BV, 2011-02-15)
The strong coupling constants of heavy baryons with light vector mesons are calculated in the framework of the light cone QCD sum rules using the most general form of the interpolating currents for the heavy baryons. It is shown that the sextet sextet, sextet-antitriplet and antitriplet-antitriplet transitions are described by one invariant function for each class of transitions. The values of the electric and magnetic coupling constants for these transitions are obtained.
