Title: A new look at QCD jets in QCD matter
Abstract: Quantum Chromodynamics (QCD) is the gauge theory of the strong interaction between quarks and gluons. Ordinary matter around us, which is governed by electromagnetism, exhibits complex collective behavior: fluids boil and flow, certain materials are superconducting, and so on. QCD matter is also thought to have complex phase structure and dynamical behavior, emerging from many quarks and gluons interacting together under finite temperature and pressure. I will discuss what we know about this fundamental state of matter, from theoretical calculations and from experiments with the collision of heavy nuclei at RHIC (Brookhaven) and the LHC (CERN). I will focus in particular on measurements of jets, correlated sprays of hadrons arising from energetic quarks and gluons, which provide well-controlled tomographic probes of such collisions.
