Abstract
If sufficiently light dibaryon resonances exist, a Bose condensate of dibaryons can occur in nuclear matter before the quark-hadron phase tr ansition. Within a relativistic mean-held model we show that heteropha se nuclear-dibaryon matter is for a wide set of parameters energetical ly more favorable than normal nuclear matter. Production of dibaryons is, however, relatively suppressed as compared to estimates based on t he model of non-interacting nucleons and dibaryons.
