چکیده

We report high statistics measurements of inclusive charged hadron production in Au+Au and p+p collisions at sqrt[s(NN)]=200 GeV. A large, approximately constant hadron suppression is observed in central Au+Au collisions for 5<p(T)<12 GeV/c. The collision energy dependence of the yields and the centrality and p(T) dependence of the suppression provide stringent constraints on theoretical models of suppression. Models incorporating initial-state gluon saturation or partonic energy loss in dense matter are largely consistent with observations. We observe no evidence of p(T)-dependent suppression, which may be expected from models incorporating jet attenuation in cold nuclear matter or scattering of fragmentation hadrons.

ct 2 00 4 High p T hadron spectra at RHIC : an overview

Abstract. Recent results on high transverse momentum (pT ) hadron production in p+p, d+Au and Au+Au collisions at the Relativistic Heavy Ion Collider (RHIC) are reviewed. Comparison of the nuclear modification factors, RdAu(pT ) and RAA(pT ), demonstrates that the large suppression in central Au+Au collisions is due to strong final-state effects. Theoretical models which incorporate jet quenchi...

A Model of Binary Collisions Dependence of Jet Quenching in Nuclear Collisions at Ultrarelativistic Energies

Hadronic spectra at high transverse momenta from ultrarelativistic nuclear collisions result from jets produced in the early hard partonic interactions. The yields are normally expected to scale with the number of binary nucleon-nucleon collisions. However, experimental results obtained at the Relativistic Heavy Ion Collider (RHIC) contradict these expectations: in central Au+Au collisions the ...

Centrality dependence of the multiplicity and transverse momentum distributions at RHIC and LHC and the percolation of strings

The dependence of the multiplicity and the transverse momentum distribution on the number of collisions are studied for central and peripheral Au-Au collisions at SPS, RHIC and LHC energies in the framework of percolation of strings. A scaling law relating the multiplicity to the mean transverse momentum is obtained. Our results are in overall agreement with the SPS and RHIC data, obtaining a s...

Antiparticle to particle ratios and identified hadron spectra in Cu+Cu and Au+Au collisions

New results on antiparticle to particle ratios in Cu+Cu and Au+Au collisions at √ s NN = 62.4 and 200 GeV from the PHOBOS experiment at RHIC are presented. Transverse momentum spectra of pions, kaons, protons and antiprotons from Au+Au collisions at √ s NN = 62.4 GeV close to mid-rapidity are also discussed. Antiparticle to particle ratios are found to be remarkably independent of the collision...

High Transverse Momentum Results from the STAR Collaboration

The STAR collaboration presents new measurements of high pT hadron production in Au+Au and p+p collisions at RHIC. We extend the previously reported suppression of inclusive hadrons and large azimuthal anisotropies to much higher transverse momentum, decisively establishing the existence of strong medium effects on hadron production well into the perturbative regime. Near-angle two-particle cor...

Jets and high pT hadrons in dense matter: recent results from STAR

We review recent measurements of high transverse momentum (high pT ) hadron production in nuclear collisions by the STAR Collaboration at RHIC. The previously observed suppression in central Au+Au collisions has been extended to much higher pT . New measurements from d+Au collisions are presented which help disentangle the mechanisms responsible for the suppression. Inclusive single hadron spec...
