The CERN Council has set itself the objective of updating the European Strategy for Particle Physics by May 2020. To achieve this, it has established a Strategy Secretariat to which it has assigned the task of organising the update process.
 

The Strategy update process will include two major events: an “Open Symposium” and a “Strategy Drafting Session”.
 

To prepare the Open Symposium, the Strategy Secretariat hereby calls upon the particle physics community in universities, laboratories, national institutes and institutions to submit written input following the enclosed guidelines.
 

The deadline for input is 18 December 2018.
 

Input should be submitted via a portal available here.

The input should consist of a document not longer than 10 pages, excluding references. Guidelines  for the expected content, where applicable, are available here and also from the submission webpage.
