Pion Suppression in Nuclear Collisions
نویسنده
چکیده
The pion multiplicity per participating nucleon in central nucleus–nucleus collisions at the energies 2–15 A·GeV is significantly smaller than in nucleon–nucleon interactions at the same collision energy. This effect of pion suppression is argued to appear due to the evolution of the system produced at the early stage of heavy–ion collisions towards a local thermodynamic equilibrium and further isentropic expansion.

Correlations in the STAR forward pion production in dAu collisions and energy losses in black disc regime
We explain that in the black disc QCD regime (BDR) in difference from the moderate x regime very forward partons propagating through the nuclear matter should loose significant, increasing with energy and atomic number fraction of their initial energy as a result of dominance of inelastic interactions, causality and energy-momentum conservation. We evaluate these small x energy losses and find ...
متن کاملEnergy losses in the black disc regime and correlation effects in the STAR forward pion production in dAu collisions
We argue that in the small x processes, in the black disc QCD regime (BDR) a very forward parton propagating through the nuclear matter should loose a significant and increasing with energy and atomic number fraction of its initial energy as a result of dominance of inelastic interactions, causality and energy-momentum conservation. We evaluate these energy losses and find them to lead to the s...
متن کاملQuenching of photon and pion spectra at intermediate RHIC energy
Single prompt photon and pion spectra in p–p and Au–Au collisions at intermediate RHIC energy, √ s NN = 62.4 GeV, are computed at large p ⊥ in perturbative QCD. Next-to-leading order calculations in p–p scattering are first presented. The quenching of the prompt photon and pion yield due to energy loss processes in central Au–Au with respect to p–p collisions is then predicted. At this energy, ...

We explore how nuclear modifications to the nucleon parton distributions affect production of high-p T hadrons in heavy ion collisions. We perform a leading order calculation of the high-p T charged pion, kaon and proton spectra using standard fragmentation functions and shadowing parameterizations. We also consider alternate models of shadowing. Near midrapidity, shadowing is a small effect an...
متن کاملJet Tomography Studies in AuAu Collisions at RHIC Energies
Recent RHIC results on pion production in AuAu collision at √ s = 130 and 200 AGeV display a strong suppression effect at high pT . This suppression can be connected to final state effects, namely jet energy loss induced by the produced dense colored matter. Applying our pQCD-based parton model we perform a quantitative analysis of the measured suppression pattern and determine the opacity of t...
