Nuclear Physics & RIKEN Theory Seminar

"Optimising jet finding in pp and AA collisions"

Presented by Gregory Soyez, Brookhaven National Laboratory

Friday, August 15, 2008, 2:00 pm — Small Seminar Room, Bldg. 510

After a generic introduction covering the recent important developments in jet physics and the need to use infrared-and-collinear-safe tools for future analysis, I will try to answer the question "what is the optimal jet algorithm for hadronic collisions?". I will show that this varies from process to process and from scale to scale, suggesting flexibility for LHC studies. Then, still in the context of finding an optimal jet finder, I will discuss practical methods to subtract soft background like pileup in the case of pp collisions or the underlying event in the case of heavy-ion collisions.
