L’Expérience : LHCb
• LHCb est un outil spécialisé, destiné à réaliser la meilleure détection possible des particules « belles » (contenant un quark b) et de leurs produits de désintégration.
LHC (Large Hadron Collider), à chaque point de collision un détecteur

Le détecteur : Calorimetre
Longueur 21mHauteur 10m5600 Tonnes
ECAL : 6000 ch
HCAL : 1500 ch
