✦ Synopsis


This paper deals with so-called Ultra-Peripheral Collisions (UPCs) of heavy ions [1,2]. These can be defined as collisions in which no hadronic interactions occur because of the large spatial separation between the projectile and target. The interactions are instead mediated by the electromagnetic field. Two types of ultra-peripheral collisions can be distinguished: purely electro-magnetic interactions (two-photon interactions) and photonuclear interactions, in which a photon from the projectile interacts with the hadronic component of the target.

An overview of recent high-p T hadron and photon measurements at RHIC is presented with a focus on the evolution of hadron/photon production from intermediate p T ( 5 GeV/c) to high p T (> 10 GeV/c). Addressed topics include single high-p T hadron production, azimuthal anisotropy of Ο€ 0 production,
