    "abstract": "The calorimeter and muon systems are essential components to provide a\ntrigger for the LHCb experiment. The calorimeter system comprises a\nscintillating pad detector and pre-shower, followed by electromagnetic and\nhadronic calorimeters. The calorimeter system allows photons, electrons and\nhadrons to be identified, and their energy to be measured. The muon system\nconsists of five measuring stations equipped with Multi-Wire Proportional\nChambers (MWPCs) and triple-Gas Electron Multiplier (GEM) detectors, separated\nby iron filters. It allows the muons identification and transverse momentum\nmeasurement. The status of the two systems and their expected performance is\npresented.",
