Calibration and performance of the LHCb calorimeters in Run 1 and 2 at the LHC

C. Abellán Beteta, A. Alfonso Albero, Y. Amhis +84

The calibration and performance of the LHCb Calorimeter system in Run 1 and 2 at the LHC are described. After a brief description of the sub-detectors and of their role in the trig…
