Nuclear Clusters as a Probe for Expansion Flow in Heavy Ion Reactions at 10-15AGeV
A phase space coalescence description based on the Wigner-function method for cluster formation in relativistic nucleus-nucleus collisions is presented. The momentum distributions of nuclear clusters d,t and He are predicted for central Au(11.6AGeV)Au and Si(14.6AGeV)Si reactions in the framework of the RQMD transport approach. Transverse expansion leads to a strong shoulderarm shape and differ...
متن کاملCollective dynamics in highly relativistic heavy-ion collisions∗
A. Dumitru Physics Department, Yale University P.O. Box 208124, New Haven, CT 06520, USA D.H. Rischke RIKEN-BNL Research Center, Brookhaven National Laboratory Upton, NY 11973, USA (September 17, 1998) We calculate the transverse momentum spectra of various hadrons and clusters (π, K, N , Φ, Λ, Ω, d, ΛΛ, He) in central Au+Au at √ s = 200A GeV (RHIC energy) up to pT = 4 GeV within hydrodynamics....
متن کاملCollective Effects in a Medium and a Model of Compound Flow in Relativistic Heavy Ion Collisions
A new analytical approach is presented for analysis of two-particle azimuthal correlations in heavy ion collisions at relativistic energies. This approach suggests that elliptic flow measured by experiment has a compound structure, namely, that it may come from superposition of several components. General expressions have been derived for the two-particle correlation function isolating the cont...
متن کاملCovariant kaon dynamics and kaon flow in heavy ion collisions
The influence of the chiral mean field on the K transverse flow in heavy ion collisions at SIS energy is investigated within covariant kaon dynamics. For the kaon mesons inside the nuclear medium a quasi-particle picture including scalar and vector fields is adopted and compared to the standard treatment with a static potential. It is confirmed that a Lorentz force from spatial component of the...
متن کاملFrom Collective Vibrations to Heavy-Ion Collisions
A summary of recent researches on nuclear dynamics with realistic microscopic quantum approaches is presented. The Balian-Vénéroni variational principle is used to derive the time-dependent Hartree-Fock (TDHF) equation describing the dynamics at the mean-field level, as well as an extension including small-amplitude quantum fluctuations which is equivalent to the time-dependent random-phase app...
