hms of jet radii R become large in jet cross sections in QCD when R is sma
ll. In exclusive jet cross sections with jets of energy Q and a veto on ad
ditional jets of energy E\, we find that logs of R come from ratios of not
one but two hierarchies of scales\, QR over Q and ER over E. We construct
an effective field theory with modes for both hard-collinear and soft-col
linear scales QR and ER\, allowing the factorization of dependences on all
scales\, and resummation of logarithms of R to arbitrarily high accuracy
in resummed perturbation theory.
