Relativistic Resonances, Relativistic Gamow Vectors and Representations of the Poincare' Semigroup
Arno R. Bohm, N. L. Harshman, M. J. Mithaiwala
The foundations of time asymmetric quantum theory are reviewed and are applied to the construction of relativistic Gamow vectors. Relativistic Gamow vectors are obtained from the r…

Relativistic Gamow Vectors II
A. Bohm, H. Kaldass, S. Wickramasekara +1
Motivated by the debate of possible definitions of mass and width of resonances for -boson and hadrons, we suggest a definition of unstable particles by ``minimally complex'' se…

Resonances, Gamow Vectors and Time Asymmetric Quantum Theory
Arno R. Bohm, Raymond Scurek, Sujeewa Wikramasekara
Decaying states can be represented by Gamow vectors with an exponential, asymmetric time evolution. This asymmetric evolution is a manifestation of irreversibility on the microphys…
