Finitesize pion effect on its selfenergy
Abstract
Effects of finite size of a pion on its selfenergy in the bag models are studied. With a scaledependent pionquark coupling the system can become stable if the pion has a finite size. If one adopts the NambuJonaLasiniotype lagrangian and relates the pionquark coupling to the confinement potential the system becomes unstable even if the pion has a finite size.
