Determination of the Equation of State of Dense Matter
Abstract
Nuclear collisions can compress nuclear matter to densities achieved within neutron stars and within corecollapse supernovae. These dense states of matter exist momentarily before expanding. We analyzed the flow of matter to extract pressures in excess of 10^{34} pascals, the highest recorded under laboratorycontrolled conditions. Using these analyses, we rule out strongly repulsive nuclear equations of state from relativistic mean field theory and weakly repulsive equations of state with phase transitions at densities less than three times that of stable nuclei, but not equations of state softened at higher densities because of a transformation to quark matter.
