Selected CMS Measurements of the Top Quark Properties in Single-top Production

Single top topologies are exploited for studies of top quark properties. This includes the first measurement of single top polarization in the t-channel production mode in pp collisions, which directly confirms the V-A nature of the tWb production vertex. W-helicity fractions are measured in the pha...

description Single top topologies are exploited for studies of top quark properties. This includes the first measurement of single top polarization in the t-channel production mode in pp collisions, which directly confirms the V-A nature of the tWb production vertex. W-helicity fractions are measured in the phase space sampled by a selection optimized for t-channel single top production, orthogonal to the ttbar final states used in traditional measurements of these properties. Anomalous couplings of the top quark are also searched in t-channel single top production with a NN-based analysis.

Anomalous couplings of the top quark are also searched in t-channel single top production with a NN-based analysis.A selected set of CMS measurements of the top quark properies in t -channel single top events together with searches for anomalous top quark couplings are presented. In particular the first tZq cross section measurement is briefly described. All results are based on the analysis of the LHC data at √ s = 8 TeV with an integrated luminosity of 19 . 7fb − 1 .SISSACMS-CR-2016-342oai:cds.cern.ch:22319102016-11-08
