Abstract
The Green's functions are constructed and a one-loop calculation is gi ven for the scalar and vector densities and for the equation of state of nuclear matter with a Bose condensate of dibaryons. This is the low est approximation in the loop expansion of quantum hadrodynamics, suff icient to account for the presence of dibaryons not in the condensate in the heterophase nucleon-dibaryon matter. It lends to a finite effec tive nucleon mass and remains consistent with increasing the density.
