Strange skyrmions: status and observable predictions

Abstract

The chiral soliton approach (CSA) provides predictions of the rich spectrum of baryonic states with different values of strangeness for any baryon number B. In the sector with B = 1, the spectrum of well known octet and decuplet of baryons can be described within the CSA, and some exotic states are predicted. In the B = 2 sector, there are many predictions of strange dibaryons, but only few - e.g., the virtual ΛN state - have been observed. Possible reasons for this are discussed.
