Mitigation of anomalous missing transverse momentum measurements in data collected by CMS at sqrt(s) = 13 TeV during the LHC Run 2

Sumario: | Proton-proton collision events with a signature of high missing transverse momentum are generally interpreted as containing high-momentum neutrinos, or possibly other invisible particles as expected in a variety of scenarios beyond the standard model, e.g. dark matter or Supersymmetry. Experimentally, detector noise or other issues can also lead to the measurement of anomalously high missing transverse momentum, thus mimicking an interesting physics signature. Various algorithms (filters) have been developed in CMS to identify and suppress such spurious events. In this note the performance of these filters is presented in events that contain at least one jet with high transverse momentum ($\rm p_{T}$). The events were recorded by the CMS experiment during the LHC Run2. |
