Ongoing studies for jet measurements in the jet physics group are listed in the tables below. Emphasis is given to the 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 efforts listed here or started new topics, feel free to add them with your name and institution and send email to the convenor.

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 over 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 approximately ~every 3 weeks. The meeting agenda can be found in the indico page of SM group meetings.
