Correct inclusion of the missing term changes the NLO cross sections and their renormalization and factorization scale dependences. As examples, Figs. 16 and 17 should be replaced by Fig. 1 below. The corrected results agree with those in Ref. [1], if CTEQ5M parton densities [2] are used along with the two-loop expression for αs and Λ (5) = 226 MeV. Our implementation of the intermediate on-shell squark subtraction in Eq. (41) differs from that in Ref. [1]. While in Ref.[1] resonance contributions are subtracted strictly on-shell, small off-shell contributions from phase space are included in our subtraction procedure. The differences are insignificant quantitatively in this case. Specific predictions for the Tevatron and LHC will be provided on request [4]. For example, we show in Fig. 2 the predicted total cross sections at the current Tevatron center-of-mass energy of √ S = 1.96 TeV for all six g̃χ̃ channels in the SUGRA model as functions of the mass of the gluino (left) and for a gluino with mass 30 GeV as functions of m1/2 (right). In Fig. 2, we use CTEQ6M (NLO) and CTEQ6L (LO) parton densities [5] and the two-loop expression for αs with Λ (5) = 226 MeV (LO and NLO).
