The 35-plet Baryons from Chiral Soliton Models

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 ∆5/2 and Θ2, which are the lightest two baryons of 35-plet with spin 5/2 and with simplest minimal pentaquark configurations. Calculations show that Γ∆5/2 <380 MeV, compared with the results from SU(2) Skyrme Model (Γ∆5/2 >800 MeV), and ΓΘ2 < 100 MeV if we assume that their widths are dominated by two-body decay and that Θ + has a width ΓΘ+ < 25 MeV.
