Exclusive dimuon production in ultraperipheral collisions (UPC), resulting from photon-photon interactions in the strong electromagnetic fields of colliding high-energy lead nuclei, $\mathrm{PbPb}(\ensuremath{\gamma}\ensuremath{\gamma})\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}({\mathrm{Pb}}^{(★)}{\mathrm{Pb}}^{(★)})$, is studied using ${\mathcal{L}}_{\mathrm{int}}=0.48\phantom{\rule{4pt}{0ex}}{\mathrm{nb}}^{\ensuremath{-}1}$ of $\sqrt{{s}_{NN}}=5.02\phantom{\rule{4pt}{0ex}}\text{TeV}$ lead-lead collision data at the LHC with the ATLAS detector. Dimuon pairs are measured …

Abstract Measurements of both the inclusive and differential production cross sections of a top-quark–antiquark pair in association with a Z boson ( $$t{\bar{t}}Z$$ t t ¯ Z ) are presented. The measurements are performed by targeting final states with three or four …

Abstract A search for long-lived particles, which have come to rest within the ATLAS detector, is presented. The subsequent decays of these particles can produce high-momentum jets, resulting in large out-of-time energy deposits in the ATLAS calorimeters. These de- cays are detected …

Several extensions of the Standard Model predict the production of dark matter particles at the LHC. An uncharted signature of dark matter particles produced in association with $VV={W}^{\ifmmode\pm\else\textpm\fi{}}{W}^{\ensuremath{\mp}}$ or $ZZ$ pairs from a decay of a dark Higgs boson $s$ is searched …

A study of the charge conjugation and parity ($CP$) properties of the interaction between the Higgs boson and top quarks is presented. Higgs bosons are identified via the diphoton decay channel ($H\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}$), and their production in association with a top quark pair …
