Self-consistent relativistic calculation of nucleon mean free path

Self-consistent relativistic calculation of nucleon mean free path.

We present a fully self-consistent and relativistic calculation of the nucleon mean free path in nuclear matter and finite nuclei. Starting from the Bonn potential, the Dirac-Brueckner-Hartree-Fock results for nuclear matter are parametrized in terms of an effective σ-ω Lagrangian suitable for the relativistic density-dependent Hartree-Fock (RDHF) approximation. The nucleon mean free path in nu...

Self-consistent Green’s functions calculation of the nucleon mean-free path

Transport coefficients provide a unique insight into the near-equilibrium behavior of quantum many-body systems. The mean-free path, λ, of a particle within a dense medium is a basic transport coefficient, at the basis of several theoretical concepts and closely related to experimentally measured quantities. Green’s functions techniques are particularly well suited to study such transport prope...

Self-consistent Green's function calculation of the nucleon mean free path.

The extension of Green's functions techniques to the complex energy plane provides access to fully dressed quasiparticle properties from a microscopic perspective. Using self-consistent ladder self-energies, we find both spectra and lifetimes of such quasiparticles in nuclear matter. With a consistent choice of the group velocity, the nucleon mean-free path can be computed. Our results indicate...

On mean free path statistics of relativistic heavy ions in nuclear emulsion

We survey at the general level, and in a rather wide and historical context, some less known mathematical details of various mean free path statistics in nuclear emulsion as applied to relativistic projectile fragmentations. A number of comments are provided on Feller’s paradox, ordered, censored, and truncated statistics, Erlang and Poisson observers of nuclear emulsion. All these issues are r...
