Learning How to Count: A High Multiplicity Search for the LHC

JHEP 08 (2013) 136

Introduces a subjet-counting search technique for high-multiplicity BSM signals at the LHC, using jet substructure to count subjets within large-radius jets and demonstrating improved sensitivity across eight benchmark signals with reduced reliance on missing energy.

High Multiplicity Searches at the LHC Using Jet Masses

Phys. Rev. D 85 (2012) 055029

Introduces a new class of BSM searches that recluster events into large-radius fat jets and require multiple massive jets, improving sensitivity to high-multiplicity signals including R-parity violating gluino decays by 20-50% in mass reach.
