The associated production of a Higgs boson and a top-quark pair is measured in events characterised by the presence of one or two electrons or muons. The Higgs boson decay into a b-quark pair is used. The analysed data, ...

Several observables sensitive to the fragmentation of b quarks into b hadrons are measured using 36 fb−1 of √s=13 TeV proton-proton collision data collected with the ATLAS detector at the LHC. Jets containing b hadrons ...
