Some Characteristic Parameters of Proton from the Bag Model (1001.0891v3)

Abstract: We treat the mass of a proton as the total static energy which can be separated into two parts that come from the contribution of quarks and gluons respectively. We adopt the essential of the bag model of hadron to discuss the structure of a proton and find that the calculated temperature, proton radius, the bag constant are compare well with QCD results if a proton is a thermal equilibrium system of quarks and gluons.
