## Abstract We consider the equations describing the local covariant unstable particle field operator as the functional of stable asymptotic decay products. In such a framework, we present two generalizations of the Yang‐Feldman equation, which can be used for the description of unstable particles.

## Abstract A density operator analysis is made of the particle‐ejection (e.g., photoionization) problem in the “generalized sudden approximation” for the case in which the ejected particle is detected but its dynamical properties are not observed. It is shown that the resultant statistical density
