Soft drop

AJ Larkoski, S Marzani, G Soyez, J Thaler - Journal of High Energy Physics, 2014 - Springer
A bstract We introduce a new jet substructure technique called “soft drop declustering”,
which recursively removes soft wide-angle radiation from a jet. The soft drop algorithm …

Loop induced single top partner production and decay at the LHC

JH Kim, IM Lewis - Journal of High Energy Physics, 2018 - Springer
A bstract Most searches for top partners, T, are concerned with top partner pair production.
However, as these bounds become increasingly stringent, the LHC energy will saturate and …

Pileup and Infrared Radiation Annihilation (PIRANHA): a paradigm for continuous jet grooming
