Performance of boosted object and jet substructure techniques in Run 1 and 2 ATLAS data
Hadronic decays of heavy particles with momenta much larger than their mass result in their decay products being reconstructable as a single large-radius jet.

Sumario: | Hadronic decays of heavy particles with momenta much larger than their mass result in their decay products being reconstructable as a single large-radius jet. The study of the substructure of these jets allows the separation of these boosted decays with respect to more common jets from light-quarks and gluons. Several techniques have been developed by the phenomenology and experimental community to identify jets coming from hadronic decays of boosted top quarks, W, Z and Higgs bosons. The performance of several such techniques have been studied in ATLAS using fully-simulated Monte Carlo events, and validated on data using pure samples of top quarks, W bosons from top decays and dijet events. Results of these studies will be presented for Run 1 as well as Run 2 of the LHC. |
