Seminar: NoPoster: No
Invited talk: Yes
In this talk I shall present a few simple examples on how the nuclear structure, nuclear density, isospin content, and finally the electric charge of the nucleus influence multiparticle production in ultrarelativistic nuclear reactions.
After a brief introduction to the phenomenology of nuclear collisions in the energy regime of a few or more GeV per incoming nucleon, I shall discuss the following physics items:
(1) The relation between the nuclear density profile and the fragmentation of the proton projectile in proton-nucleus reactions at 158 GeV/nucleon;
(2) The influence of the isospin content of the Pb nucleus on ratios of particles produced in ultrarelativistic Pb+Pb collisions;
(3) The final state electromagnetic interaction between charged pi mesons produced in the heavy ion reaction and the two nuclear remnants ("spectator systems") surviving this reaction.
If time permits, I shall also address the issue of ``neutron halo'' studies in peripheral Pb+Pb collisions at high energies.
