    "abstract": "We have introduced a CJT calculation in studying nuclear matter beyond mean\nfield approximation. Based on the CJT formalism and using Walecka model, we\nhave derived a set of coupled Dyson equations of nucleons and mesons.\nNeglecting the medium effects of the mesons, the usual MFT results could be\nreproduced. The beyond MFT calculations have been performed by thermodynamic\nconsistently determining the meson effective masses and solving the coupled gap\nequations for nucleons and mesons. The numerical results for the nucleon and\nmeson effective masses at finite temperature and chemical potential in nuclear\nmatter are discussed.",
