European Strategy Group
(CERN/3092/Rev.2 (link is external)

The European Strategy Group (ESG) is a special body set up by the CERN Council approximately every five years, with the remit to establish a proposal for the periodic update of the medium-and long-term European Strategy for Particle Physics which it submits to the CERN Council for approval. The ESG is assisted in this task by a Physics Preparatory Group (PPG, see below) and drafts its update proposal taking into account, inter alia, the scientific input submitted by the PPG. The ESG is composed of all the stakeholders of the European Strategy for Particle Physics, as follows:

 

Members:

  • the Strategy Secretary (acting as Chair),
  • one representative appointed by each CERN Member State,
  • one representative appointed by each of the Laboratories participating in the
    major European Laboratory Directors’ meetings, including its Chair
    (CERN, CIEMAT (Madrid-Spain), DESY (Hamburg-Germany), Irfu (Saclay-France), LAL (Orsay-France), Nikhef (Amsterdam-Netherlands), LNF (Frascati-Italy), LNGS (Gran Sasso-Italy), PSI (Villigen-Switzerland), STFC-RAL (Didcot-UK)),
  • the CERN Director-General,
  • the SPC Chair,
  • the ECFA Chair.
     

Invitees:

  • the President of the CERN Council,
  • one representative from each of the Associate Member States,
  • one representative from each Observer State,
  • one representative from the European Commission,

  • the Chairs of FALC and ESFRI,
  • the members of the Physics Preparatory Group.
     

Invitees are entitled to attend all open meetings of the ESG and to take the floor.

 

Physics Preparatory Group

The remit of the Physics Preparatory Group (PPG) is to prepare the scientific contribution to the work of the ESG (the “Briefing Book”), based on the input it gathers from the community. The PPG has the following composition:

 

Members:

  • the Strategy Secretary (acting as Chair),
  • four members appointed by the Council on the recommendation of the SPC,
  • four members appointed by the Council on the recommendation of ECFA,
  • the SPC Chair,
  • the ECFA Chair,
  • the Chair of the European Laboratory Directors’ meeting,
  • one representative appointed by CERN,
  • two representatives from Asia appointed by the respective regional representatives in ICFA,
  • two representatives from the Americas appointed by the respective regional
  • representatives in ICFA.

     

Strategy Secretariat

The Strategy update process is organised by the Strategy Secretariat,  which establishes a  detailed plan, approved by the CERN Council. The Strategy Secretariat prepares the work of the ESG and the PPG, organises their meetings and produces their documents. The Strategy Secretary submits the Draft Strategy Document elaborated by the ESG to the Council for approval. The Strategy Secretariat has the following composition:
