Overview of the LHCb calorimeters

Abstract : LHCb, one of the four LHC experiments, is dedicated to the study of CP violation and rare decays in the B meson sector. It aims at completing the understanding of the quark flavor physics and at revealing signs of new physics beyond the standard model. The goal of the LHCb calorimeter is twofold. On the one hand, the calorimeter system has to provide a fast response for the first level trigger (L0) on the nature of the meson decay. Thus, the scintillator pad detector and the preshower provide a good γ/ charged particle and electron/π0 separation and the electromagnetic and hadronic calorimeters give a fast transverse energy determination. On the other hand, it provides offline precision measurements and particle identification. The calorimeter system consists of four sub-detectors. They are described in the first section, emphasising the technical choices and the similarities among those components. The second part concerns the monitoring and calibration tools and procedures that will be applied to have a satisfactory running of the detector.
