Description
CMS detector at CERN-LHC has a two level trigger system to filter events that are stored for further analysis. The Level-1 trigger is based on fast electronics. The events passing the Level-1 trigger have to then go through the High Level Trigger (HLT), which is based on a computing farm. The HLT menu consists of a large number of HLT paths based on various selections on reconstructed physics object(s) in a given event. The object reconstruction at HLT is optimized to run faster due to the timing constraints and, therefore, less accurate than the offline reconstruction. It is crucial to properly reconstruct jets and missing transverse energy at the high level trigger for the success of precision measurements and new physics searches at LHC, since many physics signatures at LHC include jets and missing transverse energy in their final state. In this talk we will present the performance of the jet and missing transverse energy reconstruction at HLT during the LHC Run-2. The performances are measured in terms of efficiencies and resolutions with respect to that of offline reconstructed objects.
