Nuclear Theory/RIKEN Seminar

"Evolution of the jet opening angle distribution in holographic plasma"

Presented by Andrei Sadofyev, MIT

Friday, May 13, 2016, 2:00 pm — Small Seminar Room, Bldg. 510

Energetic jets are particularly interesting probes of QGP created in heavy ion collisions. Recently a lot of progress was made in attempting to describe the jet evolution in holography. In this talk I'll present an application of a simple dual model to study the jet substructure starting with energy and angle distributions from pQCD. In particular I will show that there are two competing effects: (1) each individual jet widens as it propagates through plasma; (2) the final jet opening angle distribution becomes narrower since wider jets lose more energy and less likely to survive. So, the mean opening angle for jets with a given energy can easily shift toward smaller angles, even while every jet in the ensemble broadens.
