Identification and Mitigation of Anomalous Signals in CMS Hadronic Calorimeter

Abstract

The CMS HCAL detector occasionally records anomalous large energy signals that correspond to particles hitting the transducers. Anomalous signals in HCAL can also be produced by rare random discharges of the readout detectors. We present a summary of various sources of anomalous signals, the algorithms developed to identify them, and the performance of these algorithms in the CMS collision data.
