Measurement of Missing Transverse Energy in CMS Experiment

摘要

202.1 Introduction Particles that go undetected inside a detector are the main cause of missing transverse energy or MET or E~(miss)_T. By definition,{formula} where {→ under letter p}~i_T is the transverse momentum of the i~(th) detected particle, like muons, electrons or hadrons produced by hadronization of quarks and gluons. The momentum imbalance due to detector resolution and sensitivity of the detector to various identified particles must be scrutinised thoroughly before relevant physics interpretation. In practice, the MET is corrected for the potential effects of the detector measurements and details of event reconstruction algorithms.
