How CMS cleaned up 85’000’000’000’000’000 bytes without touching any original, raw data!
CMS has recently conducted the largest deletion campaign in its history, deleting roughly 85 Petabytes (85’000’000’000’000’000 bytes) of data from the magnetic tapes, in order to free up space for the Run 3 collisions.

Flavoured Mysteries: searching for the tau lepton’s 3 muon decay
It was 1918 when the mathematician Emmy Noether published what is known as her most famous theorem, revealing the fundamental relation between the symmetries of a physical system and the laws enforcing the conservation of some of its characteristic quantities.

What if there was a second and lighter Higgs boson?
In 2012, the ATLAS and CMS Collaborations observed a new boson with a mass of 125 GeV, whose properties are compatible with those of the Higgs boson predicted by the Standard Model (SM) of particle physics.
