The top quark, discovered 1995 at Fermilab, is special among the quarks due to its large mass: Its lifetime is shorter than the characteristic hadronization time scale and therefore top bound states do not have time to form. From a calculational point of view this allows an immediate application of perturbation theory to top physics. Up to now top quarks have only been produced in pairs through...

Single Top and Top Pair Production

Differential Cross Sections for Top-pair and Single-top Production

NNLL Threshold Resummation for Top-pair and Single-top Production

I discuss threshold resummation at NNLL accuracy in the standard moment-space approach in perturbative QCD for top-pair and single-top production. For top quark pair production I present new approximate NNLO results for the total cross section and for the top quark transverse momentum and rapidity distributions at 8 TeV LHC energy. I discuss the accuracy of the soft-gluon approximation and show...

Search for Single-top Production at Cdf

This article reports on recent searches for single-top-quark production by the CDF collaboration at the Tevatron using a data set that corresponds to an integrated luminosity of 955 pb. Three different analyses techniques are employed, one using likelihood discriminants, one neural networks and one matrix elements. The sensitivity to single-top production at the rate predicted by the standard m...
