The HL-LHC project is an international endeavour that began in November 2011 and was announced as the top priority of the 2013 update of the European Strategy for Particle Physics. Since the approval of the design report in 2015, prototypes have been tested at CERN, and the time is now ripe to start racing towards new physics.

The upgraded machine will deliver a higher number of proton-proton collisions per second, thanks to the increased luminosity. More collisions means more chances for physicists to investigate rare phenomena and collect more accurate measurements. 

If you are interested in attending this event, please send your pre-accreditation to by Monday, 11 June.
