New Family of Exotic Θ-Baryons

الأصل · EN

From the interpretation of the Θ+ baryon resonance as an excitation of the ``skyrmion liquid'' with SU(3) flavor symmetry 10 we deduce a new series of baryons, Θ₁⁺⁺, Θ₁⁺ and Θ₁⁰, situated at the top of the 27-plet of SU(3) flavor, with hypercharge Y=2, isospin T=1 and spin J=32. The mass of Θ₁ is estimated 55 MeV/c² higher then the mass of Θ+ and its width at 80 MeV. We also discuss the other baryons from the 27-plet.
