The Standard Model explains how the basic building blocks of matter interact, governed by four fundamental forces. The theories and discoveries of thousands of physicists since the 1930s have resulted ...

Measurements in fundamental physics are becoming increasingly difficult. In particular, many high-precision measurements are now dealing with the intrinsic quantum mechanical noise of the detectors ...

Tim Berners-Lee, a British scientist, invented the World Wide Web (WWW) in 1989, while working at CERN. The Web was originally conceived and developed to meet the demand for automated ...

Bus line no. 66 (Thoiry Centre commercial <-> Geneva Airport) provides a regular daily service to Prévessin-CERN, passing through Saint-Genis Porte de France.

The High-Luminosity LHC, which is expected to be operational after 2025, will increase the LHC’s luminosity by a factor of 10. Luminosity is an important indicator of the performance of an accelerator ...

The “Standard Model” of particle physics is a set of equations that describes accurately how a small number of fundamental particles interact, and how they form visible matter. But we know that this ...
