Query: Sequential recombination algorithm for jet clustering and background
  subtraction   We investigate a new sequential recombination algorithm which effectively
subtracts background as it reconstructs the jet. We examine the new algorithm's
behavior in light of existing algorithms, and we find that in Monte Carlo
comparisons, the new algorithm's robustness against collision backgrounds is
comparable to that of other jet algorithms when the latter have been augmented
by further background subtraction techniques.
