The Interpretation of Quantum-Mechanical Models with Non-Hermitian Hamiltonians and Real Spectra
R. Kretschmer, L. Szymanowski
We study the quantum-mechanical interpretation of models with non-Hermitian Hamiltonians and real spectra. We set up a general framework for the analysis of such systems in terms o…

Collinear Asymptotic Dynamics for Massive Particles. Multi-Channel Regge Behaviour
J. Boguszynski, H. D. Dahmen, R. Kretschmer +1
The high-energy behaviour in a multi-channel system is investigated in the framework of collinear asymptotic dynamics for massive particles. We consider the most general trilinear…

Collinear Asymptotic Dynamics for Massive Particles. Reggeization and Eikonalization
J. Boguszynski, H. D. Dahmen, R. Kretschmer +3
The dynamics of massive particles in the collinear high momentum regime is investigated. Methods hitherto exploiting large time asymptotic Hamiltonians in the Dirac picture for the…
