Description
The quenching of jets in heavy ion collisions is one of the clearest signatures of the formation of a deconfined state of quarks and gluons, known as the Quark Gluon Plasma (QGP). The semi-inclusive measurement of jets recoiling from a high-𝑝T hadron (hadron+jet) in heavy ion collisions uniquely enables the exploration of medium-induced modification of jet production and acoplanarity over a wide phase space, including the low jet 𝑝T region for large jet resolution parameter 𝑅. This technique crucially provides a precise data-driven subtraction of the large uncorrelated background contaminating the measurement.
This talk will report semi-inclusive measurements of hadron-jet yield and acoplanarity in pp and Pb-Pb collisions at 5.02 TeV, and of jets with different 𝑅. Special focus will be given to the recent measurement of the first fully-corrected hadron+jet azimuthal correlation (Δ𝜙) distribution.
