Description
When a massless, isospinor Dirac field is confined to a finite region of space by means of a chiral boundary condition parametrized by an angle theta, the baryon number of the vacuum is shown to be (chi/2π)(theta-sintheta costheta) where chi is the Euler characteristic of the bounding surface. Some implications for chiral bag models are discussed
