Abstract
The performance of missing transverse momentum (\({\vec p}_{\mathrm{T}}^\mathrm{miss}\)) 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 \({\vec p}_{\mathrm{T}}^\mathrm{miss}\), and detailed studies of events identified with anomalous \({\vec p}_{\mathrm{T}}^\mathrm{miss}\). The performance is presented of a \({\vec p}_{\mathrm{T}}^\mathrm{miss}\) reconstruction algorithm that mitigates the effects of multiple proton-proton interactions, using the "pileup per particle identification" method. The performance is shown of an algorithm used to estimate the compatibility of the reconstructed \({\vec p}_{\mathrm{T}}^\mathrm{miss}\) with the hypothesis that it originates from resolution effects.
