Abstract
We reexamine the single top-quark production process, which is important at the CERN LHC, unlike what happens at the Fermilab Tevatron. Special attention is paid to the treatment of the process and part of its next-to-leading correction, the process. We show that the process has to be correctly taken into account with a proper subtraction of the top-pair contribution, and that it has qualitatively different kinematical distributions from the process. We present the total cross section of the production as being about 62 pb, and at the proper QCD scale equal to the top quark mass, suggest a method of combining the and processes with gauge-invariant subtraction of the part, which allows us to reproduce the kinematical properties correctly and perform a proper event simulation of the process in the whole kinematical region.
