Tagging highly boosted top quarks

Studies of Highly-boosted Top Quarks Near the TeV Scale Using Jet Masses at the LHC

Measurement of the differential cross-section of highly boosted top quarks

The differential cross-section for pair production of top quarks with high transverse momentum is measured in 20.3 fb−1 of proton-proton collisions at a center-of-mass energy of 8 TeV. The measurement is performed for tt events in the leptonþ jets channel. The cross-section is reported as a function of the hadronically decaying top quark transverse momentum for values above 300 GeV. The hadroni...

A Search for Boosted Top Quarks by CDF II

We present the results of a search for boosted top quarks in a sample of high transverse momentum jets observed in the CDF II detector. The data were selected from a sample of 5.95 fb−1 of 1.96 TeV proton-antiproton collisions at the Fermilab Tevatron. We observe 57 candidate events in a sample where we require two massive jets or one massive jet with significant missing transverse energy, with...

Long Short-Term Memory (LSTM) networks with jet constituents for boosted top tagging at the LHC

Multivariate techniques based on engineered features have found wide adoption in the identification of jets resulting from hadronic top decays at the Large Hadron Collider (LHC). Recent Deep Learning developments in this area include the treatment of the calorimeter activation as an image or supplying a list of jet constituent momenta to a fully connected network. This latter approach lends its...
