On the Theory of the Unstable Particle in Lee's Model

Abstract:

In Lee's model of the renormalizable field some investigations are made on the possibility of choosing the mass mV of a physical V-particle to be larger than the sum of the masses of an N- and a θ-particle (namely, the case mV > mN + µ). If the mass m0 of a bare V-particle is chosen to be larger than some particular value, it seems to be possible to describe an unstable V-particle by Lee's model without any inconsistency, and to give a prescription for the renormalization of such an unstable particle. In this argument a method is used which is somewhat similar to that used in the theory of α-decay. Finally a brief discussion is made on the anomalous states.
