Parallel session talk Beyond the Standard Model Beyond the Standard Model


Yanlin Liu (University of Michigan (US))


Many new-physics signatures at the LHC produce highly boosted particles, leading to close-by objects in the detector and necessitating jet substructure techniques to disentangle the hadronic decay products. This talk will focus on the tagging methods recently developed within the ATLAS collaboration to identify boosted top-quarks, vector- and Higgs-bosons. It will also illustrate the use of these tagging techniques in physics analyses, including recent diboson and top-antitop resonance searches, as well as searches for vector-like quarks or dark matter, using the full Run 2 dataset.
