| Popis: | We present the complete threshold enhanced predictions in QCD for the total cross section of gluino pair production at hadron colliders at next-to-next-to-leading order. Thanks to the computation of the required one-loop hard matching coefficients our results are accurate to the next-to-next-to-leading logarithm. In a brief phenomenological study we provide predictions for the total hadronic cross sections at the LHC and we discuss the uncertainties arising from scale variations and the parton distribution functions. Comment: 25 pages, 7 figures, 5 tables, v2: references added, figures added, expanded discussion of the hadronic cross section, typo in eq. (B.4) corrected |
