N2 - The first observation of top quark production in proton-nucleus collisions is reported using proton-lead data collected by the CMS experiment at the CERN LHC at a nucleon-nucleon center-of-mass energy of ffiffiffiffiffiffiffiffi sNNp ¼ 8.16 TeV.Themeasurementisperformedusingeventswithexactlyoneisolatedelectronormuon candidate and at least four jets. The data sample corresponds to an integrated luminosity of 174 nb−1. The significance of the t¯ t signal against the background-only hypothesis is above 5 standard deviations. The measured cross section is σt¯ t ¼ 458 nb, consistent with predictions from perturbative quantumchromodynamics.
