Pion self-energy in the chiral bag model

Abstract

The pion self-energy due to the presence of the quark-antiquark pair within the bag is calculated. It is found to grow like N~ as the number N of the qq-pair intermediate states becomes large. Efforts to explain all particle phenomena in view of the gy, v the radial quantum number, K = f ( j + f) ( j is the quark picture have acquired brilliant successes. The MIT total angular momentum), and p the azimuthal quantum bag model,',2 and the succeeding work3 are along this line.number. chin6 calculated the contribution of the intermedi-One tried, with these models, to calculate the mass structure ate states and the magnetic moments of particles.2,4 The models promise us a bright future in one way.
