Time Asymmetric Quantum Theory - III. Decaying States and the Causal Poincare Semigroup

A. Bohm, H. Kaldass, S. Wickramasekara

A relativistic resonance which was defined by a pole of the -matrix, or by a relativistic Breit-Wigner line shape, is represented by a generalized state vector (ket) which can b…

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…

Semigroup Representations of the Poincare Group and Relativistic Gamow Vectors

A. Bohm, H. Kaldass, S. Wickramasekara +1

Gamow vectors are generalized eigenvectors (kets) of self-adjoint Hamiltonians with complex eigenvalues describing quasistable states. In the relativistic domain…

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…

Relativistic Partial Wave Analysis Using the Velocity Basis of the Poincare Group

A. Bohm, H. Kaldass

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…

Irreversible Quantum Mechanics in the Neutral K-System

Arno Bohm

The neutral Kaon system is used to test the quantum theory of resonance scattering and decay phenomena. The two dimensional Lee-Oehme-Yang theory with complex Hamiltonian is obtain…
