A measurement is reported of the jet mass distribution in hadronic decays of boosted top quarks produced in pp collisions at √ s = 13 TeV. The data were collected with the CMS detector at the LHC and correspond to an integrated luminosity of 35.9 fb−1. The measurement is performed in the lepton+jets channel of tt events, where the lepton is an electron or muon. The products of the hadronic top quark decay t → bW → bqq ′ are reconstructed as a single jet with transverse momentum larger than 400…

The CMS experiment makes use of a large variety of algorithms to identify the origin of particle jets measured in the detector. Through the study of jet substructure properties, jets originating from
Standard model parameters from top quark measurements at LHC with ATLAS and CMS
Theoretical predictions for standard model (SM) processes involving top quarks, such as top quark-antiquark pair or single top production, depend on fundamental SM parameters like the strong coupling
Jets and Jet Substructure at Future Colliders
Even though jet substructure was not an original design consideration for the Large Hadron Collider (LHC) experiments, it has emerged as an essential tool for the current physics program. We examine

TLDR
This manual describes the design choices that have been made in the Contur tool, as well as detailing pitfalls and common issues to avoid, and hopes that with the help of this documentation, external groups will be able to run their own Contur studies, for example when proposing a new model, or pitching a new search.
