Suppressing the spurious states of the centre of mass
P. Dita, L. Micu
Following Dirac's ideas concerning the quantization of constrained systems, we suggest to replace the free centre of mass Hamiltonian H_{CM} by another operator which commutes with…
Comments on a bound state model for a two body system
L. Micu
We show that in classical mechanics, as well as in nonrelativistic quantum mechanics the equation of the relative motion for a two-body bound system at rest can be replaced by indi…
A Lorentz covariant representation of bound state wave functions
L. Micu
We present a method enabling us to write in relativistic manner the wave function of some particular two particle bound state models in quantum mechanics. The idea is to expand the…
Dispersion relations and Omnès representations for decay amplitudes
C. Bourrely, I. Caprini, L. Micu
We derive dispersion relations for decay, using the Lehmann-Symanzik-Zimmermann formalism, which allows the analytic continuation of the amplitudes with respect to the mom…
Analytical solutions of a Dirac bound state equation and their field interpretation
L. Micu
We solve the single particle Dirac bound state equation with a particular confining potential and comment its significance from the point of view of the quantum field theory. We sh…
A stationary relativistic representation of the bound state
L. Micu
We show that a bound system in momentum space can be treated like a gas of free elementary constituents and a collective excitation of a background field which represents the count…
