Description
Summary:A formalism for treating the scattering of decuplet baryons in chiral effective field theory is developed. The minimal Lagrangian and potentials in leading-order SU(3) chiral effective field theory for the interactions of octet baryons ( B ) and decuplet baryons ( D ) for the transitions BB → BB , BB ↔ DB , DB → DB , BB ↔ DD , DB ↔ DD , and DD → DD are provided. As an application of the formalism we compare with results from lattice QCD simulations for Ω Ω and N Ω scattering. Implications of our results pertinent to the quest for dibaryons are discussed.
