Discovery of Single Top Quark Production at D0 - Joint D0/CDF Seminar

Presented by Shabnam Jabeen, Boston University

CDF and D0 experiments at the Fermilab Tevatron proton-anti prtoton
collider have recently observed the production of single top quark
events. This is one of the most anticipated results from Tevatron Run
II. In this talk, I will present the analysis that lead to this
discovery at the D0 experiment.


Observation of electroweak single top production at CDF - Joint D0/CDF Seminar

Presented by Fabrizio Margaroli, Purdue University

The top quark has been discovered at the Tevatron collider in 1995 in
events where it is produced in pairs. The standard model predicts that
top quarks can be produced singly through the electroweak force, the
cross section being proportional to V_tb^2; the less striking
signature made much more difficult to reach the observation level to
this rare process. In march 2009, the Tevatron experiments have
finally achieved this important milestone. I will present in this talk
the CDF analysis, the techniques we used, and finally the cross
section we measure.
