What happens after a particle collision takes place?
Why do we need so many collisions? What can they tell us?

In this three-part series, named “Particle collisions”, we address all these questions, and much more.

Beam tests boost #FCC detector technologies 🔬

The recent beam tests #AtCERN offered the first opportunity to evaluate two new calorimeter technologies under study for International Detector for Electron Accelerator (IDEA), both of which showed promise for future large-scale developments.
