CMS experiment delves into the mystery of neutrino masses

An animation made with TED-ED to explore empty space and why it is important for experiments at CERN

The Large Hadron Collider has established a new record of luminosity, delivering a huge amount of data to its experiments

The LHC has been accelerating more and more protons, and to allow the machine to reach its maximum intensity, it will undergo a thorough scrubbing.

Data-taking has started again at the LHC: the experiments are continuing their exploration of physics at the unprecedented energy of 13 TeV.

Adjustments to the thousands of pieces of equipment making up the LHC are ongoing before data taking can start for 2017

For the first time this year, the LHC is circulating beams of protons, following a 17-week-long extended technical stop

We meet Rende Steerenberg, who is the group leader for the accelerator and technical teams

We are now being taken into the complex realm of higher-order calculations, with an explosion of activity in recent months

See in images how the “heart” of the CMS detector, its Pixel Tracker, was replaced
