A bstract Measurements of both the inclusive and differential production cross sections of a top-quark-top-antiquark pair in association with a Z boson ( $$ t\overline{t}Z $$ t t ¯ Z ) are presented. Final states with two, three or four isolated leptons …

Combined measurements of Higgs boson production cross sections and branching fractions are presented. The combination is based on the analyses of the Higgs boson decay modes $H\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}$, $Z{Z}^{*}$, $W{W}^{*}$, $\ensuremath{\tau}\ensuremath{\tau}$, $b\overline{b}$, $\ensuremath{\mu}\ensuremath{\mu}$, searches for decays into invisible final states, and on measurements …

Abstract The algorithms used by the ATLAS Collaboration during Run 2 of the Large Hadron Collider to identify jets containing b -hadrons are presented. The performance of the algorithms is evaluated in the simulation and the efficiency with which these algorithms identify …

This Letter presents a search for exotic decays of the Higgs boson to a pair of new (pseudo)scalar particles, H → a a , where the a particle has a mass in the range 20–60 GeV, and where one of the a …
