Multifragmentation in Relativistic Heavy Ion Reactions
Multifragmentation is the dominant decay mode of heavy nuclear systems with excitation energies in the vicinity of their binding energies. It explores the partition space associated with the number of nucleonic constituents and it is characterized by a multiple production of nuclear fragments with intermediate mass. Reactions at relativistic bombarding energies, exceeding several hundreds of Me...
متن کاملThe Vector Probe in Heavy-Ion Reactions
We review essential elements in using the J = 1− channel as a probe for hot and dense matter as produced in (ultra-) relativistic collisions of heavy nuclei. The uniqueness of the vector channel resides in the fact that it directly couples to photons, both real and virtual (dileptons), enabling the study of thermal radiation and in-medium effects on both light (ρ, ω, φ) and heavy (Ψ,Υ) vector m...
متن کاملSymmetry energy determination in heavy ion collisions
BEL~M(A,Z) = a,A asA2’3aJ2/A”3 + a,A“‘* asym (N-Z)2/A (1) where N, Z and A are the neutron, proton and mass numbers; a,, a, and a, are the volume, surface and Coulomb terms in the liquid drop model. aPA-“* is the pairing energy. The last term in Eq. (l), asym (N-Z)‘/A, accounts for the symmetry energy which favors nuclei with equal number of protons and neutrons. In most parametrizations, asym ...
متن کاملChiral Symmetry Restoration and Dileptons in Relativistic Heavy-Ion Collisions
The current theoretical status in the analysis and interpretation of low-mass dilepton measurements in (ultra-) relativistic heavy-ion experiments is reviewed. Special emphasis is put on potential signals of (partial) restoration of dynamically broken chiral symmetry in a hot and dense hadronic medium. It follows from chiral symmetry alone that parity partners of hadronic correlation functions ...
متن کاملStopping in Relativistic Heavy Ion Reactions From SIS to RHIC
The status of stopping in heavy ion reactions is reviewed by comparing available data in pp, pA and AA systems over the energy regime √ sNN ≈ 2.5− 130 GeV. The data consist of average rapidity losses, anti-proton over proton ratios, and net-baryon values at mid-rapidity. The overall features of nuclear stopping are reasonbly well described by simple extrapolations of pp, and pA collisions to AA.
