Standard Model Jet Physics Working Group

Convenor : Koji Terashi

Overview

The jet physics group, recently formed as a new sub-group in the Standard Model physics group, will discuss common issues and progress of analyses on jet physics measurements such as inclusive jets, dijet and multi-jet production and kinematics, jet properties, and the jet production in diffractive and exclusive processes.

Meetings

Jet physics sub-group meetings will be scheduled at 15:00 on Friday in a week before P&P/ATLAS weeks. The meeting agenda can be found in the indico page of SM group meetings. Additional meetings will be scheduled on demand.
Next meeting: 2010 Feb. 19th

Analysis Activities

People and Ongoing Projects

Ongoing activities for each analysis topic and people are listed in the tables below. Emphasis will be given to studies aimed for early measurement and jet performance studies where a large overlap with Jet/EtMiss combined performance group is seen. If you have joined these efforts listed here or started new topics, feel free to add them with your name and institution and send email to the convenor.
