The 35-plet Baryons from Chiral Soliton Models
Abstract
We investigate the 35-plet baryons from the chiral soliton models. We find that the coupling constant for the decay of 35-plet baryons with spin 3/2 to the decuplet baryons is surprisingly small, but that for the decay to 27-plet baryons with spin 3/2 is larger. We give all the masses and widths of 35-plet baryons with spin 5/2 and suggest candidates for all nonexotic members from the available particle listings. We also focus on and , which are the lightest two baryons of 35-plet with spin 5/2 and with simplest minimal pentaquark configurations. Calculations show that 380 MeV, compared with the results from SU(2) Skyrme Model (800 MeV), and MeV if we assume that their widths are dominated by two-body decay and that has a width MeV.
