Abstract
Using a recently proposed approximation for multiskyrmion fields based on rational maps we study the masses and baryonic radii of some strange multibaryons within the bound state soliton model. We find a S=−4 tetrabaryon which seems to be lighter than the previously known tetralambda. In addition, the model predicts the existence of a “heptalambda” which is stable against strong decays.
