Analysis of resonance production using relativistic Gamow vectors
H. Kaldass
The calculation of an amplitude involving resonance production is presented. This calculation employs for the resonance state a relativistic Gamow vector. It is used for investigat…
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…
Hilbert Space or Gelfand Triplet - Time Symmetric or Time Asymmetric Quantum Mechanics
A. Bohm, H. Kaldass, P. Patuleanu
Intrinsic microphysical irreversibility is the time asymmetry observed in exponentially decaying states. It is described by the semigroup generated by the Hamiltonian $\QTR{it}{H}$…
