New physics searches at the LHC or Tevatron typically look for a specific number of hard jets, leptons and photons. To obtain an exclusive N-jet sample, one can measure the event shape "N-jettiness" \tau_N and veto additional undesired jets by requiring \tau_N XL, where a central jet veto \tau_B 0, we obtain a factorization formula with inclusive jet and beam functions that allows us to sum the large logarithms of \tau_N.
