Abstract
We derive a very simple expression for the total decay rate of an unstable particle analogous to the optical theorem, and demonstrate its equivalence with the total decay rate defined in terms of the imaginary part of the propagator pole. The common origin of mass shifting and total decay rate is also demonstrated.
