Recursive Soft Drop

Dreyer, Frédéric A., Necib, Lina, Soyez, Gregory et al.

Understand

We introduce a new jet substructure technique called Recursive Soft Drop, which generalizes the Soft Drop algorithm to have multiple grooming layers.

Like the original Soft Drop method, this new recursive variant traverses a jet clustering tree to remove soft wide-angle contamination.
By enforcing the Soft Drop condition N times, Recursive Soft Drop improves the jet mass resolution for boosted hadronic objects like W bosons, top quarks, and Higgs bosons.
We further show that this improvement in mass resolution persists when including the effects of pileup, up to large pileup multiplicities.
