Shaking the box for new physics

The CMS collaboration has searched for new physics in a rare decay of a known particle, using an approach that can be likened to shaking a box containing a birthday present to find a clue about what’s inside

CMS measures rare particle decay with high precision

Using LHC Run 2 data, CMS has precisely measured the rare decay of strange B-mesons to muon-antimuon pairs. While its properties agree with Standard Model predictions, it may provide clues to new discoveries in Run 3
