Relativistic Nucleus-Nucleus Collisions: from the BEVALAC to RHIC
I briefly describe the initial goals of relativistic nuclear collisions research, focusing on the LBL Bevatron/Bevalac facility in the 1970’s. An early concept of high hadronic density fireball formation, and subsequent isentropic decay (preserving information as to the high density stage) led to an outline of physics observables that could determine the nuclear matter equation of state at seve...
متن کاملFast Neutron Dose Mapping in a Linac Radiotherapy Facility
CR-39 plastic detectors were used for fast neutron dose mapping in the radiotherapy facility at King AbdulAziz University Hospital (KAUH). Detectors were calibrated using a Cf neutron source and a neutron dosimeter. After exposure chemical etching was performed using 6N NaOH solution at 70 C. Tracks were counted using an optical microscope and the number of tracks/cm was converted to a neutron ...
متن کاملDilepton production in proton-proton collisions at BEVALAC energies
The dilepton production in elementary pp → eeX reactions at BEVALAC energies Tlab = 1 ÷ 5 GeV is investigated. The calculations include direct ee decays of the vector mesons ρ, ω, and φ, Dalitz decays of the π, η-, ρ-, ω-, and φ-mesons, and of the baryon resonances ∆(1232), N(1520), . . . . The subthreshold vector meson production cross sections in pp collisions are treated in a way sufficient ...
متن کاملDilepton Production and M T -scaling at Bevalac/sis Energies *
We present a dynamical study of e + e − production in C + C and Ca + Ca collisions at BEVALAC/SIS energies on the basis of the covariant transport approach HSD employing momentum-dependent ρ-meson spectral functions that include the pion modifications in the nuclear medium as well as the polarization of the ρ-meson due to resonant ρ−N scattering. We find that the experimental data from the DLS ...
متن کاملe+e− production from pp reactions at BEVALAC energies
We have performed a detailed study of dilepton production from pp collisions including the subthreshold ρ production via baryonic resonances (N(1520), N(1700)) in addition to the conventional dilepton sources as π0, η, ω and ∆ Dalitz decays and direct decays of vector mesons (ρ, ω). The role of baryonic resonances in ρ production from nucleon-nucleon collisions is studied in comparison to the D...
