European Strategy Group for High Energy Physics

The European Strategy Group for High Energy Physics advises the CERN Council and coordinates long-term planning for particle physics across Europe, interfacing with major projects such as the Large Hadron Collider, the Future Circular Collider study, and proposals linked to the European Union research framework. It synthesizes inputs from laboratories like CERN, national agencies including the STFC, INFN, CNRS, and funding bodies such as the ERC and the European Investment Bank to shape priorities influencing experiments at facilities like DESY, GSI Helmholtz Centre for Heavy Ion Research, and proposals related to ITER-adjacent technologies.

History

The group's origins trace to deliberations by the CERN Council after deliberations following milestones such as the LEP shutdown and the construction phase of the Large Hadron Collider, with early influence from figures who had led projects like ATLAS, CMS, ALICE, and LHCb. Its formalization followed strategy exercises resembling the Particle Physics Project Prioritization Panel process in the United States and strategic reviews like the High Energy Physics Advisory Panel in the United Kingdom, influenced by outcomes from conferences such as ICHEP and task forces convened after discoveries including the Higgs boson announcement. Successive strategy updates have responded to technological advances from collaborations involving Fermilab, KEK, SLAC National Accelerator Laboratory, and multinational consortia exemplified by the International Linear Collider proposals and the Compact Linear Collider study.

The group is appointed by and reports to the CERN Council and comprises representatives from member and associate member states such as France, Germany, Italy, Switzerland, Spain, Sweden, Poland, Netherlands, Belgium, and observer delegations including United States Department of Energy-affiliated scientists and delegations from Japan and China. Membership includes directors and scientists drawn from institutions such as CERN, DESY, INFN, CNRS, Fermilab, KEK, and national agencies including the Science and Technology Facilities Council, Deutsches Elektronen-Synchrotron, and the Polish Academy of Sciences. The group interacts with standing panels and working groups containing experts from experiments like ATLAS, CMS, LHCb, instrumentation projects such as RD50, and accelerator initiatives including HL-LHC.

Its mandate, defined by the CERN Council and shaped by precedent from advisory entities such as the European Research Council, is to produce a prioritized European strategy for high energy physics to guide decisions affecting projects like the High-Luminosity LHC, proposals for the Future Circular Collider, and advanced detector programs feeding into collaborations with DUNE and Hyper-Kamiokande. Functions include soliciting input from the community via bodies like the European Committee for Future Accelerators, commissioning studies with institutions such as GSI Helmholtz Centre for Heavy Ion Research and CERN TH, and issuing recommendations that influence funding by agencies like the European Commission and national ministries in capitals such as Paris, Berlin, Rome, and Brussels.

Strategy updates follow cycles similar to previous exercises timed after major conferences like EPS-HEP and ICHEP; the process issues calls for input to laboratories such as CERN, universities including University of Oxford, University of Cambridge, École Polytechnique, and can convene open meetings in cities like Geneva and Prague. The group establishes topical working groups drawing experts from collaborations including ATLAS, CMS, ALICE, LHCb, accelerator R&D teams from SLAC National Accelerator Laboratory and Fermilab, and theory communities affiliated with institutes such as Institute for Advanced Study, Max Planck Society, and CEA. Final strategy documents undergo discussion at CERN Council sessions and informal briefings to ministers in forums such as ESFRI and liaison activities with the European Commission.

Past recommendations shaped major undertakings: endorsement of the High-Luminosity LHC upgrade accelerated commitments from France, Germany, Italy, and United Kingdom agencies and enabled detector upgrades in ATLAS and CMS; support for studies of machine concepts influenced momentum behind the Compact Linear Collider and the Future Circular Collider initiative; prioritization of neutrino physics strengthened European roles in DUNE and Hyper-Kamiokande. The group's guidance has impacted budgets administered by bodies like the European Investment Bank and national ministries, affected collaborations with Fermilab, KEK, and prompted R&D programs at laboratories including DESY and GSI Helmholtz Centre for Heavy Ion Research.

The group functions as an advisory arm to the CERN Council while coordinating with national funding agencies such as the STFC, INFN, CNRS, Deutsches Forschungsgemeinschaft, and ministries in capitals like London, Paris, and Rome to align continental priorities with national programs. It mediates between laboratory-scale projects at CERN, accelerator design efforts at DESY and GSI Helmholtz Centre for Heavy Ion Research, and national roadmaps overseen by agencies such as the European Research Council and the European Commission, facilitating multinational partnerships with institutions including Fermilab, KEK, SLAC National Accelerator Laboratory, and university consortia.
