Ben Nachman (LBNL) and Mateus Ploskon (LBNL) "Jet Substructure"

August 31, 2017 @ 4:00 pm - 5:00 pm

The LBNL xTalk (“cross-talk”) series provides a forum for the exchange of ideas between groups and across lab divisions.  Each seminar is focused on a theme which is confronted from two perspectives.  In particular, the talks are given by two presenters from different domains. The format is informal (chalk talk!) and is designed to be entertaining and engaging.  Come prepared to learn and ask about details with the experts in order to stimulate collaborations between groups.  We hope that this will strengthen the program at the lab and spread new ideas.
For the first xTalk, we will have Mateusz Ploskon from Nuclear Science and Benjamin Nachman from the Physics Division to discuss how jet substructure is used in ALICE/STAR and in ATLAS. Jets are collimated sprays of particles resulting from quarks and gluons produced at high energy. The radiation pattern within jets encodes a wealth of information about the parton that initiated it. Jet substructure is a hot topic in pp for tagging boosted W/Z/H bosons and also recently for precision probes of Quantum Chromodynamics (QCD); in heavy ion collisions, jet substructure is an exciting new probe of medium modifications. Please join us for this comparative discussion of how jet substructure is used in two very different environments!
