Resummation of jet-veto logarithms in hadronic processes containing jets

Understand

We derive a factorization theorem for production of an arbitrary number of color-singlet particles accompanied by a fixed number of jets at the LHC.

• The jets are defined with the standard anti-$k_T$ algorithm, and the fixed number of jets is obtained by imposing a veto on additional radiation in the final state.
• The formalism presented here is useful for current Higgs boson analyses using exclusive jet bins, and for other studies using a similar strategy.
• The derivation uses the soft-collinear effective theory and assumes that the transverse momenta of the hard jets are larger than the veto scale.
