Potential, strangeness, pion

A microscopic optical potential for elastic proton-nucleus scattering has been derived at the first-order term within the spectator expansion of the non-relativistic multiple-scattering theory and adopting the impulse approximation.

Two-basic ingredients are required to build the optical potential: a model for nuclear densities and the $NN$ interaction. For the $NN$ interaction we have used...

Potential, strangeness, pion

Motivated by a renewed interest of hypernucleus studies, strangeness degree of freedom was implemented in the intranuclear cascade model INCL.

INCL takes care of the first stage of reactions between a nucleon (or a light cluster) and a nucleus at energies from a few tens of MeV up to a few GeV. After emission of fast particles, a hot remnant nucleus is produced and then another model,...

79. Isospin of pions - what do they tell us about the neutron skin of nuclei?

Potential, strangeness, pion

The isospin of pions has long time been discussed as signal of the equation of state of asymetric matter. Especially in collisions of heavy ions (like Au+Au) at energies of several hundred MeV, the ratio of negative and positive pions has been proposed to be sensitive to isospin dependent potentials. However, the conclusions from comparison to experimental FOPI data have been rather...
