Performance of Missing Transverse Momentum Reconstruction in Proton-proton Collisions at Toot s=13 TeV Using the CMS Detector
The performance of missing transverse momentum (ÆpmissT) reconstruction algorithms for the CMS experiment is presented, using proton-proton collisions at a center-of-mass energy of 13 TeV, collected at the CERN LHC in 2016. The data sample corresponds to an integrated luminosity of 35.9 fb−1. The results include measurements of the scale and resolution of ÆpmissT,and detailed studies of events identified with anomalous ÆpmissT. The performance is presented ofaÆpmissT reconstruction algorithm that mitigates the effects of multiple proton-proton interactions,using the “pileup per particle identification” method. The performance is shown of an algorithmused to estimate the compatibility of the reconstructedÆpmissTwith the hypothesis that it originatesfrom resolution effects.
