Using jets as a tool to probe the trillion degree quantum liquid of strong force*

• Heavy-ion collisions have been a fascinating venue to study the Quantum Chromo-Dynamics (QCD), the theory of strong force, under extreme conditions.  When the nuclei collide, an exotic phase of matter, the quark-gluon plasma (QGP), is created.  The QGP is believed to have existed in the early universe microseconds after the big bang.  Jets, sprays of particles originating from high energy quarks or gluons, are one of the interesting probes of heavy-ion collisions due to their extended size and nontrivial colored interaction with the hot medium.  The study of jets in heavy-ion collisions provides insights into the underlying interaction mechanisms between jets and the QGP, shedding light on the properties of the medium itself.  In this talk I will summarize some of the latest results from jet studies in heavy ion collisions and what we have learned from them, and where we might go from here.
