A search optimized for new heavy particles decaying to two $b$-quarks and produced in association with additional $b$-quarks is reported. The sensitivity is improved by $b$-tagging at least one lower-${p}_{\mathrm{T}}$ jet in addition to the two highest-${p}_{\mathrm{T}}$ jets. The data used in …

Abstract Several improvements to the ATLAS triggers used to identify jets containing b-hadrons (b-jets) were implemented for data-taking during Run 2 of the Large Hadron Collider from 2016 to 2018. These changes include reconfiguring the b-jet trigger software to improve primary-vertex finding …

A search for new phenomena is presented in final states with two leptons and one or no b-tagged jets. The event selection requires the two leptons to have opposite charge, the same flavor (electrons or muons), and a large invariant mass. The …

A search for the standard model Higgs boson produced in association with a top-quark pair, $t\overline{t}H$, is presented. The analysis uses $36.1\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of $pp$ collision data at $\sqrt{s}=13\text{ }\text{ }\mathrm{TeV}$ collected with the ATLAS detector at the Large Hadron Collider …
