Diffractive J/ψ production in Ultraperipheral AuAu Collisions at RHIC

CHARMONIUM AND BOTTOMONIUM PRODUCTION IN pp COLLISIONS AT CDF

We present measurements of charmonium and bottomonium production using a data sample collected by CDF during the 1992-93 pp collider run at the Fermilab Tevatron. Previous CDF measurements of J/ψ and ψ(2S) production during the 1988-89 collider run showed production cross sections considerably larger than contemporary theory predicted. This drew theoretical interest, but at the time the questio...

Jet 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...

Pion Interferometry in Auau Collisions at √ S Nn =200 Gev

We present preliminary results from a two-pion intensity interferometry analysis from Au+Au collisions at √ s NN =200 GeV measured in the STAR detector at RHIC. The dependence of the apparent pion source on multiplicity and transverse momentum are discussed and compared with preliminary results from d+Au and p+p collisions at the same beam energy.

Self-similarity of strangeness production in pp collisions at RHIC

New experimental data on transverse momentum spectra of strange particles (K S ,K −,K∗, φ, ...) produced in pp collisions at √ s = 200 GeV obtained by the STAR and PHENIX collaborations at RHIC are analysed in the framework of z-scaling approach. Scaling properties of the data z-presentation are illustrated. Self-similarity of strange particle production is discussed. A microscopic scenario of ...
