Search for Single Vectorlike Quarks in pp Collisions at {radical}(s)=1.96 TeV
We present a search for hypothetical vectorlike quarks in pp collisions at {radical}(s)=1.96 TeV. The data were collected by the D0 detector at the Fermilab Tevatron Collider and correspond to an integrated luminosity of 5.4 fb{sup -1}. We select events with a final state composed of a W or Z boson...

| description | We present a search for hypothetical vectorlike quarks in pp collisions at {radical}(s)=1.96 TeV. The data were collected by the D0 detector at the Fermilab Tevatron Collider and correspond to an integrated luminosity of 5.4 fb{sup -1}. We select events with a final state composed of a W or Z boson and a jet consistent with a heavy object decay. We observe no significant excess in comparison to the background prediction and set limits on production cross sections for vectorlike quarks decaying to W+jet and Z+jet. These are the most stringent limits to date for electroweak single vectorlike quark production at hadron colliders. |
