  • The information of the equation of state of cold nuclear matter is extracted from the experimental nuclear masses by the droplet model. The result shows the asymmetry dependence of the equation of state in a more direct way than has been done before. It shows that the spherical or the deformed nuclear region appears alternately as the bulk nucleon density of the core of nuclei increases. An explanation of why the rms fit of the droplet model to the nuclear masses gives a very broad minimum region of the nuclear compressibility is possible based on this work.
  • The nuclear density overlap, which occurs during refractive heavy-ion scattering, opens an alternative approach to study the equation of state (EOS) for cold nuclear matter. For this purpose elastic [sup 16]O+[sup 16]O scattering at incident enegies of 145, 250, 350, and 480 MeV has been measured very accurately, up to large angles. A systematic folding analysis of these data has been performed using an effective density dependent interaction based on the [ital G]-matrix elements of the Paris nucleon-nucleon potential. We find, with the observed refractive scattering patterns, that a soft EOS (with the nuclear incompressibility [ital K] around 200 MeV)more » is the most realistic one.« less
  • Various functional parametrizations of the equation of state of cold nuclear matter are considered with regard to both their degree of stiffness and their causal behavior at high density. We show that (i) the inferred nuclear compressibility K is strongly parametrization dependent when the measured pion multiplicity in central heavy ion collisions is fitted, and (ii) most of the commonly used equations of state are acausal at high density.
  • I examine the role of final state interactions in cold nuclear matter in modifying hadron production on nuclear targets with leptonic or hadronic beams. I demonstrate the extent to which available experimental data in electron-nucleus collisions can give direct information on final state effects in hadron-nucleus and nucleus-nucleus collisions. For hadron-nucleus collisions, a theoretical estimate based on a parton energy loss model tested in lepton-nucleus collisions shows a large effect on midrapidity hadrons at fixed target experiments. At energies currently available at the BNL Relativistic Heavy Ion Collider, the effect is large for negative rapidity hadrons but mild at midrapidity.more » This final state cold hadron quenching needs to be taken into account in jet tomographic analysis of the medium created in nucleus-nucleus collisions.« less
  • We investigate the splitting and mixing of {rho} and {omega} mesons in nuclear matter. The calculations were performed on the basis of QCD sum rules and include all operators up to mass dimension-6 twist-4 and up to first order in the coupling constants. Special attention is devoted to the impact of the scalar four-quark condensates on both effects. In nuclear matter the Landau damping governs the {rho}-{omega} mass splitting while the scalar four-quark condensates govern the strength of individual mass shifts. A strong in-medium mass splitting causes the disappearance of the {rho}-{omega} mixing.
