An important factor comes from the madgraph simulation at LO, that accounts for some phenomena that I don't know which it is. Apparentely, if one tries to find the luminosity from the number of generated events and the process cross section, it's 1.2 times smaller than the result of MadGraph. Unfortunately, at NLO, MadGraph don't give any luminosity, and it must be calculated usgin this procedure. Using that factor of 1.2 only in the NLO generated BG processes, the new k-factors are:
