Relive 2020 at CERN

Highlights of the year at CERN, from engineering and accelerator milestones to particle physics results and much more


From the awakening of CERN’s new linear accelerator Linac4 to major upgrades across the accelerator complex and detectors, it has been a year of change to the CERN infrastructures.

In the midst of a global pandemic, CERN scientists joined forces with experts in healthcare, drug development, epidemiology and emergency response in the fight against COVID-19.

Yet, despite the year’s challenges, the CERN community produced many beautiful physics results, from the discovery of a new tetraquark to the first indications of a rare Higgs boson process and the opening of an avenue for high-precision studies of the strong force.

This video will take you on a journey through key moments of 2020 at CERN. Enjoy!
