Title: Jet quenching at RHIC. What have we learned?

Abstract

Partonic energy loss (jet quenching) within the hot and colored medium created in heavy-ion collisions is one of the essential tools to provide quantitative understanding of Quark Gluon Plasma. Measurements of jet quenching via single and di-hadron observables have provided initial estimates of the energy density of the medium. However, these hadron-triggered observables suffer from well-known biases since they fold production cross-sections with the energy loss itself, providing limited information on the initial energy of the propagating jet. Fully reconstructed jets - in terms of energy flow - will allow a complete exploration of fragmentation patterns and will not suffer from geometrical biases, providing deeper understanding of partonic energy loss. We recall the pioneering hadron triggered measurements, summarize their impact and put them in contrast to the recent measurements of fully reconstructed jets in heavy-ions at RHIC.
