Wednesday 2 September 2015 Speaker: Dr Craig Sawyer (RAL/PPD) Title: "Precision V+jet measurements using the ATLAS detector" Abstract: After introducing myself to the PPD group, I will discuss the work I carried out during my PhD on ATLAS, particularly in the realm of jet calibration in high pile-up environments and the precision measurement of vector boson production in association with jets. Namely, I will discuss the ATLAS W+jet and R-jet measurements and the challenges they pose for experiment and theory alike.
