Single Top as Window on Heavy Quarks and Other New Physics
Cross-sections as predicted by the SM with 3 generations and as measured for single top production. Standard model predictions are at next-to-leading order with next-to-next-to-leading logarithm resummation  for a top mass of 173 GeV and MSTW2008 NNLO parton distribution functions. The first theory uncertainty is from scale variation (), and the second is from the parton distribution function at 90% confidence level. When two experimental uncertainties are quoted, the first is statistical and the second is systematic, and when a third uncertainty is quoted it corresponds to the luminosity uncertainty.
