ALICE Physics Organization

Physics Board

The Physics Board (PB) coordinates and assesses activities concerning physics analyses and measurements. These activities are the focus of eight Physics Working Groups (PWGs), whose conveners are members of the PB. The PB also acts, in close connection with the Editorial Board and Conference Committee, as the steering group for the preparation of physics publications, notes and oral presentations.


The Physics Board formulates proposals to the MB and to the TB for the optimization of physics performance and the definition of running conditions. The activities of the PB and PWGs are presented in regular ‘Physics Forum’ meetings open to all Members of the Collaboration.

PB meetings

  • Weekly Meetings (open to the Collaboration after minutes approval, 5-6 days after the meeting)
