Description
Jets represent an important tool to explore the properties of the hot
and dense nuclear matter created in heavy-ion collisions. However,
their reconstruction presents a challenging task due to the extremely
large and fluctuating background that overwhelm the true hard jet
population.
We present recent measurements of charged jets in
Au+Au collisions, by the STAR collaboration at RHIC, where the
background is suppressed via a new technique based on event mixing and
via a cut on leading hadron transverse momentum.
The measured observables are the inclusive jet yield and the
semi-inclusive yield of recoil jets from a high pT hadron trigger.
These jet measurements allow a direct comparison of jet quenching at RHIC
and the LHC and provide new constraints on theoretical calculations of jet
quenching.
