Self-consistent determination of QMC model parameters in nuclear matter

It is discussed the equivalent properties between QMC and QHD models, and then, the in-medium QMC model parameters are determined self-consistently. The results demonstrate that the bag constant and the nucleon radius are greatly influenced by nuclear medium, however, the parameter for the zero-point motion keeps the same value as in vacuum. The critical curve shows that the QMC model parameters determined in our scheme are valid in low density region (rho less than or equal to 1.75 rho(0)) to discuss the finite nuclei and nuclear matter properly.
