Higher Order Perturbation Corrections of Rotating Excited States in the Standard SU(3) Skyrme Model to Baryon Mass Spectrum

The higher order corrections of SU(3) rotating excited states to the Gell-Mann-Okubo Relations (or GOR) are presented in the standard SU(3) Skyrme model.The Improved GOR (or IGOR) are obtained. The results show the IGOR for decuplet up to the third order and for octet up to the second order are much compatible with the experimental data. But things becomes quite inadequate for the octet to the third order. In order to overcome the inadequacy, a heuristic discussion is presented. The properties of SU(3) rotating excited states 27-let(with spin 1/2 or 3/2),10$^*$-let (with spin 1/2) and 35-let (with spin 3/2) are also discussed.

Electromagnetic Masses of the Massive Yang-Mills Particles K^*(892)

Electromagnetic mass difference between neutral $K^*$ and charged $K^*$ has been calculated in the $U(3)_L\times U(3)_R$ chiral fields theory of mesons. It has been revealed that the non-abelian gauge structure of the massive Yang-Mills lagrangian obeyed by $K^*$ plus VMD (vector meson dominace) causes the EM-mass of neutral one larger than charged one. Experiment supports this effect.

Bethe Ansatz and Quantum Davey-Stewartson 1 System with Multicomponent in Two Dimensions

The quantum 2-component DS1 system was reduced to two 1D many-body problems with $δ-$function interactions, which were solved by Bethe ansatz. Using the ansatz in ref.[1] and introducing symmetric and antisymmetric Young operators of the permutation group, we obtain the exact solutions for the system.

Second Order Perturbation Corrections to Baryon Mass Spectrum in Skyrmion Quantum Mechanics

The corrections to the Gell-Mann-Okubo relations of baryon-masses are presented in the SU(3) Skyrme model. These corrections are calculated up to the second order in flavor breaking at the skyrmion quantum mechanics. The results are compatible with the experimental data. They could be regarded as a signal of existence of some obscure SU(3)-multiplets: 27-let(with spin 1/2 or 3/2),10$^*$-let(with spin 1/2) and 35-let(with spin 3/2).
