    "abstract": "The equation of state of symmetric nuclear matter with the inclusion of\nnon-strange dibaryons is studied. We pay special attention to the existence of\na dibaryon condensate at zero temperature. These calculations have been\nperformed in an extended quark-meson coupling model with density-dependent\nparameters, which takes into account the finite size of nucleons and dibaryons.\nA first-order phase-transition to pure dibaryon matter has been found. The\ncorresponding critical density is strongly dependent on the value of the\ndibaryon mass. The density behavior of the nucleon and dibaryon effective\nmasses and confining volumes have also been discussed.",
