Strong enhancement of extremely energetic proton production in central heavy ion collisions at intermediate energy.
نویسندگان
چکیده
The energetic proton emission has been investigated as a function of the reaction centrality for the system (58)Ni + (58)Ni at 30A MeV. Extremely energetic protons (E(NN)(p) > or = 130 MeV) were measured and their multiplicity is found to increase almost quadratically with the number of participant nucleons, thus indicating the onset of a mechanism beyond one- and two-body dynamics.

Intermediate mass dilepton production in heavy-ion collisions at SPS energies
Through the analysis of HELIOS-3 data on dilepton spectra, we demonstrate the importance of secondary processes for the dilepton production in heavy-ion collisions in the intermediate mass region. We find that, while the dilepton spectra in proton-induced reactions can be nicely explained by the decay of primary vector mesons, charmed hadrons, and initial Drell-Yan processes, the strong enhance...
متن کاملHigh transverse momentum identified particle spectra in 200 GeV collisions from STAR
Significant baryon over meson enhancement was measured at RHIC in the intermediate transverse momentum range of pT = 2−4 GeV/c (”baryonmeson puzzle”). With STAR detector we were able to extend particle identification towards higher transverse momentum offering further insights into the particle production mechanisms at intermediate to high pT . In this paper we present results on charged pion, ...
متن کاملStrangeness and Antibaryon Production in Heavy-Ion Collisions
We review the experimental results on strangeness and antibaryon production in heavy-ion collisions at the AGS and SPS. We argue that the observed enhancement in kaon production at the AGS is consistent with hadronic description, while the multistrange baryon and antibaryon results at the SPS may need physics beyond hadronic nature. We call the need for measurements of low energy antilambda-pro...

The intermediate p T region (2-5 GeV/c) in central Au+Au collisions at RHIC has a rich physics content. The (anti)proton to pion ratio at the intermediate p T gives us a powerful tool to investigate the bulk properties of the hot and dense matter created at RHIC and their hadronization processes. We present the preliminary results of identified charged hadron spectra at the lower beam energies ...
متن کاملEffects of Dense Matter on Hadron Production in Heavy-ion Collisions
The intrinsic transverse momentum distribution of partons in the nucleon can be used to explain a large amount of high-pT hadron and photon production data in high-energy nucleon-nucleon collisions at energies √ s ≈ 20 to 1800 GeV. However, proton-nucleus experiments at energies ≈ 30 GeV show an extra enhancement (Cronin effect) in the yield of photons and mesons compared to a simple extrapolat...
