## Idea

The LHCb experiment is one detector/experiment within the Large Hadron Collider (“LHC”) with focus on the physics of B-mesons (similar to the Belle experiment).

After the discovery of the Higgs field at the two major other detectors of LHC, the LHCb experiment currently stands out as seeing hints for physics beyond the standard model of particle physics with considerable statistical significance: the flavour anomalies (see there for more).
