Rigged Hilbert Space Resonances and Time Asymmetric Quantum Mechanics
A. Bohm, H. Kaldass
The Rigged Hilbert Space (RHS) theory of resonance scattering and decay is reviewed and contrasted with the standard Hilbert space (HS) theory of quantum mechanics. The main differ…

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…
