Nuclear Physics Seminar - Ben Wu (CERN) - Resummation of Boson-Jet Correlation at Hadron Colliders

Arun Paramekanti (University of Toronto) 4/6/20 Quantum Matter seminar
July 2, 2019
11:00 am - 12:00 pm
M2035 Physics Research Building

In this talk, I will talk about our recent work on the calculation of the transverse momentum distribution (\vec{q}_T) of the boson+jet system in boson production events in pp collisions. Here, \vec{q}_T is the vector sum of the transverse momenta of the boson and the jet. We resum logarithms log(Q/q_T) and logR at next-to-leading logarithmic accuracy including the non-global logarithms, where Q and R are respectively the hard scattering energy and the radius of the jet. I will also talk about the measurement of the jet quenching parameter \hat{q} by studying such events in heavy-ion collisions.
