ct 2 00 4 High p T hadron spectra at RHIC : an overview
نویسنده
چکیده
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 quenching via gluon Bremsstrahlung in the dense partonic medium that is expected in central Au+Au collisions at ultra-relativistic energies are shown to reproduce the shape and magnitude of the observed suppression over the range of collision energies so far studied at RHIC.

New experimental data on inclusive spectra of identified particles produced in pp collisions at the RHIC are used to test z-scaling. Energy and multiplicity independence of the scaling function is established. The RHIC data confirm z-scaling observed at U70, ISR, SpS and Teva-tron energies. The obtained results are of interest to search for new physics phenomena of particle production in high t...

Ultra-relativistic heavy ion collisions at RHIC and the LHC open exciting new possibilities for jet physics studies in the presence of hot and dense nuclear matter. Recent theoretical advances in understanding the QCD multi-parton dynamics provide a good description of the quenching in the single and double inclusive high-pT hadron spectra. Measurement of the redistribution of the lost energy a...
متن کاملIdentified Particle Spectra and Jet Interactions with the Medium
Through a combination of detector upgrades and advancements in analysis techniques, physicist at RHIC are extending their ability to identify particles at high p T. With these new capabilities some outstanding questions are being addressed: particularly regarding baryon production. Here I present an overview of new data on identified particle elliptic flow (v 2), identified particle p T spectra...

A simple thermal model with single freeze-out and flow is used to analyze the ratios of hadron yields and the hadron transverse-mass spectra measured in √ sNN = 130 GeV Au+Au collisions at RHIC. An overall very good agreement between the model predictions and the data is achieved for all measured hadron species including hyperons.

Exclusive vector meson photoproduction, pp → ppV and pp → ppV occurs with significant rates at hadron colliders. The reaction can be used to study the gluon distribution of protons. Vector mesons may be produced with either proton as a target; because of interference between the two production channels, the pT spectra of vector mesons produced in pp and pp collisions are quite different.
