High order corrections for top quark and jet production at the Tevatron
Abstract
Description
An overview of the theoretical status of the top quark and single-jet inclusive production cross sections at the Tevatron is presented. NLO results as well as NNLO-NNLL and higher order threshold expressions derived from resummation calculations are discussed. Numerical results are presented for top quark production at the Tevatron, and it is shown that higher orders contribute sizable corrections to the total cross section and differential distributions, and they also dramatically reduce the factorization scale dependence of the cross section. For jet production, the scale dependence is also reduced but the NNLO threshold corrections are not very big.
