Measurements of Single-Top Quark Production at the Tevatron
Abstract
The latest measurements of the cross sections for singly-produced top quarks at the Fermilab Tevatron are presented. The small expected signals and the large, uncertain backgrounds require careful event selection, sophisticated methods for separating signal events from background events, and data-based background predictions and fits. Both the CDF and D0 collaborations have solid evidence of single top production, using 2.7 fb-1 and 0.9 fb-1 of data, respectively. Both collaborations perform several analyses to measure the total single-top cross section sigmas + sigmat, as well as sigmas and sigmat separately.
