Semi-classical approach to sequential recombination algorithms for jet
clustering    [PDF]

Jeff Tseng, Hannah Evans

We derive a new sequential recombination algorithm for reconstructing jets of particles in high-energy collision events from a simple, semi-classical model of successive uniform massless emissions. The model results in a different distance measure used to determine the sequence of clustering steps, and 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.
