✦ Synopsis

The zero-point energy of a massive scalar field confined to a two-dimensional M. I. T. bag model, is calculated. Since the cutoff sum over modes cannot be explicitly summed, the Green's function method, developed earlier, is applied. The Green's function is constructed by two different methods and the results compared. Divergences which occur when the cutoff is removed can be absorbed into a redefinition of the bag constant. The effect of the remaining finite piece of the zero-point energy on the bag energy spectrum is studied.
