Search for the associated production of a single top quark and a Z or Higgs boson with the CMS experimentM.

The acceptance for single top quark events for these selections is 0.2–0.3% per channel, which should yield ≈ 1 tagged event (tb and tqb, with electron and muon W decays combined)..

Outputs from the five neural networks used to separate t-channel tqb signal from background in the untagged electron+jets decay channel.. For each plot, the upper curve with error

The search for top quark decays in the leptonic channel is based on the selection of events with high P T leptons and missing transverse momentum described in [8].. Further details
