We have three new papers about to be published that mark some of the most important Heavy Ion measurements to date, addressing how colored particles lose energy as they traverse the quark gluon plasma created in our relativistic heavy ion collisions. The first measurement we made probes how high energy quarks and gluons fragment as they pass through the hot colored medium and into the vacuum. The second clarifies how these high energy particles lose energy depending of how much medium they pass through. The final paper uses back-to-back pair of photon and quark or gluon to directly probe the absolute amount of energy loss.
