Optimisation of large-radius jet reconstruction for the ATLAS detector in 13 TeV proton-proton collisions
(Springer, 2021-04)
Jet substructure has provided new opportunities for searches and measurements at the LHC, and has seen continuous development since the optimization of the large-radius jet definition used by ATLAS was performed during Run ...

Performance of pile-up mitigation techniques for jets in pp collisions at root s=8 TeV using the ATLAS detector
(Springer, 2016-10-27)
The large rate of multiple simultaneous proton–proton interactions, or pile-up, generated by the Large Hadron Collider in Run 1 required the development of many new techniques to mitigate the adverse effects of these ...

Search for new phenomena with top quark pairs in final states with one lepton, jets, and missing transverse momentum in pp collisions at root s=13 TeV with the ATLAS detector
(Springer, 2021-04-19)
A search for new phenomena with top quark pairs in final states with one isolated electron or muon, multiple jets, and large missing transverse momentum is performed. Signal regions are designed to search for two-, three-, ...
Measurement of the top quark mass in the t(t)over-bar -> dilepton channel from root s=8TeVATLAS data
(Elsevier, 2016-10-10)
The top quark mass is measured in the channel () using ATLAS data recorded in the year 2012 at the LHC. The data were taken at a proton–proton centre-of-mass energy of and correspond to an integrated luminosity of about ...
