[1] The European Strategy is mandated by the CERN Council, and is formed through a broad consultation of the grass-roots particle physics community.
[2] The European Strategy takes into account the worldwide particle physics landscape and developments in related fields, and was initiated by the CERN Council to coordinate activities across a large, international and fast-moving community with the aim to maximise scientific returns.
[4] The Large Hadron Collider (LHC) was cited as the top scientific priority of European particle physics with a discussion of a possible significant luminosity upgrade.
Other priorities included research and development of future accelerators, coordination with a potential International Linear Collider, and participation in a global neutrino program.
An update to the original European Strategy was prepared in 2012 and formally adopted in 2013 following the discovery of the Higgs boson.
