Hadron mass and the properties of nuclear matter in the quark bag models

The MIT bag model, chiral bag model and cloudy bag model are revisited. A t ypical work on the hadron mass calculation by chiral bag model and cloudy b ag model is shown in more details with the quark-quark-pi vertex correction and quark self-energy being emphasized. More details are given to review t he quark-meson coupling model and its application in nuclear matter. We put ; forth the Lagrangian of the quark-meson coupling model and studied the po ssibility of using the model to calculate the hadron mass.
