โœฆ Synopsis

We show how the state of an unstable particle can be defined in terms of stable asymptotic states. This general definition is used to discuss and to solve some old problems connected with the short-time and large-time behaviour of the non-decay amplitude.

Relativistic quantum fields can be classified according to the way they transform under Lorentz transformations. More specifically, they transform according to irreducible representations of the Lorentz group. The different representations give rise to particles with different values of the spin ang
