A state vector description for relativistic resonances is derived from the first order pole of the jth partial S-matrix at the invariant square mass value [Formula: see text] in the second sheet of the Riemann energy surface. To associate a ket, call

Relativistic Gamow vectors emerge naturally in a time asymmetric quantum theory as the covariant kets associated to the resonance pole \(s=s_R\) in the second sheet of the analytically continued S-matrix. They are eigenkets of the self-adjoint mass o

The velocity basis of the Poincare group is used in the direct product space of two irreducible unitary representations of the Poincare group. The velocity basis with total angular momentum j will be used for the definition of relativistic Gamow vect

Relativistic resonances and decaying states are described by representations of Poincar\'e transformations, similar to Wigner's definition of stable particles. To associate decaying state vectors to resonance poles of the $S$-matrix, the conventional
