Baryon Antidecuplet in the Chiral Quark-Soliton Model
Abstract
In the present talk, we review a series of recent investigations on the structure of the baryon antidecuplet, in particular, of the Θ+ baryon within the framework of the chiral quark-soliton model. Taking into account the 1/Nc rotational and linear ms corrections, we calculate the mass splittings of the SU(3) baryons, and the vector and axial-vector transition form factors. We discuss the results in the context of recent experimental data. We also briefly show very recent results of the electromagnetic mass splittings of the baryon antidecuplet in a "model-independent" approach, which will provide a basic setting for the physical mass splittings of the SU(3) baryons.
