In this paper we investigate analytic properties of sextet polynomials hexagonal systems. For the pyrene chains, show that zeros $$P_n(x)$$ are real, located in open interval $$(-3-2\sqrt{2},-3+2\sqrt{2})$$ and dense corresponding closed interval. We also coefficients symmetric, unimodal, log-concave, asymptotically normal. general systems, real all $$(-\infty ,0]$$ , conjecture every polynomia...

We consider the minimal supersymmetric extension of the 3-3-1 model and we study the mass spectra in the scalar sector of this model without the anti-sextet. We show that all our lighest scalars are in agreement with the experimental limits.

Computed off-nucleus magnetic shielding isosurfaces and contour plots provide a feature-rich picture of aromaticity bonding breathe new life into Clar's aromatic sextet theory.

Kekule structures are transformed into the subspace of their double bonds to yield the correspondilng factor graphs, orig.inally called submolecules (8. E 1Bas i 1, Internat. J. Quantum Chem. 21 (1982) 771). A graiph-theoretical analysis of factor graphs is presented for certain classes o,f benzeno1i:d hydrocarbons. Such an analysis led to expressions for .the construction of sextet polynomials...

We give a general formulation of the quark diagram scheme for the nonleptonic weak decays of baryons. We apply it to all decays of the antitriplet and sextet charmed baryons and express their decay amplitudes in terms of the quark-diagram amplitudes, including the e ects of nal-state interactions. (We also point out the mistaken results in the literature.) We obtain many relations among various...

First non-trivial chiral corrections to the magnetic moments of triplet (T ) and sextet (S) heavy baryons are presented using Heavy Hadron Chiral Perturbation Theory. The contributions are calculated up to order O(1/(mQΛχ)) for T -baryons and up to order O(1/Λχ) for S-baryons. The renormalization of the chiral loops is discussed and relations among the magnetic moments of different hadrons are ...
