Observation of top quark production in proton-nucleus collisions. Physical Review Letters, 119(24). doi:10.1103/PhysRevLett.119.242001 | Abstract: | 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 sNN=8.16 TeV. The measurement is performed using events with exactly one isolated electron or muon candidate and at least four jets. The data sample corresponds to an integrated luminosity of 174 nb-1. The significance of the tt signal against the background-only hypothesis is above 5 standard deviations. The measured cross section is σtt=45±8 nb, consistent with predictions from perturbative quantum chromodynamics. | URI: | http://doi.org/10.1103/PhysRevLett.119.242001 http://hdl.handle.net/11147/6750 |
