Natural Units
Our universe is governed by a handful of fundamental constants, such as the speed of light or the gravitational constant. In particle physics, it is often convenient to use natural units, in which key constants are set to unity, revealing the underlying simplicity of physical laws.

ATLAS Open Virtual Visit
Join us for an Open ATLAS Virtual Visit, hosted by ATLAS physicists Christian Appelt and Despoina Sampsonidou.
This live virtual event will take you inside the ATLAS cavern at CERN, offering a rare opportunity to see the ATLAS detector up close before the cavern is closed for LHC operation. From 100 meters underground, the hosts will guide you around one of the world’s largest and most sophisticated scientific instruments.
Pile-Up
Sheet Type
Pile-Up
The LHC collides bunches (groups of protons), which can result in multiple proton-proton collisions at each crossing. Such additional collisions are called pile-up.
