Mr FLORENT LACROIX (UIC/FERMILAB)
In this talk we report comprehensive results of studies of missing transverse energy (MET) measured by the CMS detector in pp collisions at a centre-of-mass energy of 7 TeV. Three MET reconstruction algorithms are deployed for various physics analyses. The scale and resolution for MET are validated using vector boson and dijet events, and severe mismeasurements due to the detector are studied. We also parametrize the effects of multiple pp interactions within the same bunch crossings on the scale and resolution. A tool, called MET significance, based on particle resolutions in each event is also presented.
