Power corrections in the N jettiness subtraction scheme
We discuss the leadinglogarithmic power corrections in the Njettiness subtraction scheme for higherorder perturbative QCD calculations. We compute the nexttoleading order power corrections for an arbitrary Njet process, and we explicitly calculate the power correction through nexttonexttoleading order for colorsinglet production for both $$q\bar{q}$$ and gg initiated processes. Our results are compact and simple to implement numerically. Including the leading power correction in the Njettiness subtraction scheme substantially improves its numerical efficiency. Finally, we discuss what features of our techniques extend to processes containing finalstate jets.
