摘要
The next-to-leading order QCD corrections to the Standard Model process of single top production, bg --> tW(-), for the CERN Large Hadron Collider with roots = 14 TeV have been calculated. For renormalization and factorization scales mu = mu(0) (mu(0) = m(t) + m(W)), the NLO hadronic cross section is similar to 42 pb, while similar to 26.5 pb for tree level. The NLO QCD corrections can enhance the cross section by a factor from 1.4 to 1.7 for mu(0)/2 < mu mu 2mu(0). (C) 2002 Elsevier Science B.V. All rights reserved.
