Strange Multiskyrmions
Using the 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 the tetralambda
binding to be stronger than previously expected. In addition, the model
predicts the existence of a ``heptalambda'' which is stable against strong
decays.Comment: 8 pages, Latex, no figure
Multibaryons with heavy flavors in the Skyrme model
We investigate the possible existence of multibaryons with heavy flavor
quantum numbers using the bound state approach to the topological soliton model
and the recently proposed approximation for multiskyrmion fields based on
rational maps. We use an effective interaction lagrangian which consistently
incorporates both chiral symmetry and the heavy quark symmetry including the
corrections up to order 1/m_Q. The model predicts some narrow heavy flavored
multibaryon states with baryon number four and seven.Comment: 8 pages, no figures, RevTe
