This Letter presents results from a combination of searches for Higgs boson pair production
using 126$-$140 fb $^{-1} $ of proton-proton collision data at $\sqrt {s}= 13$ TeV recorded …

Z boson events at the Large Hadron Collider can be selected with high purity and are
sensitive to a diverse range of QCD phenomena. As a result, these events are often used to …

A bstract A search is performed for light, spin-0 bosons decaying into two photons in the 66
to 110 GeV mass range, using 140 fb− 1 of proton-proton collisions at\(\sqrt {s}\)= 13 TeV …

A bstract A search for dark mesons originating from strongly-coupled, SU (2) dark flavor
symmetry conserving models and decaying gaugephobically to pure Standard Model final …

A bstract A search for a hypothetical heavy scalar particle, X, decaying into a singlet scalar
particle, S, and a Standard Model Higgs boson, H, using 140 fb− 1 of proton-proton collision …

A search is presented for the pair production of heavy vectorlike quarks (VLQs) that each
decay into a W boson and a light quark. This study focuses on events where one W boson …

A bstract A search for neutral long-lived particles (LLPs) decaying in the ATLAS hadronic
calorimeter using 140 fb− 1 of proton-proton collisions at\(\sqrt {s}\)= 13 TeV delivered by the …

Inclusive cross-sections for top-quark pair production in association with charm quarks are
measured with proton–proton collision data at a center-of-mass energy of 13 TeV …

A bstract Cross-section measurements for a Z boson produced in association with high-
transverse-momentum jets (p T≥ 100 GeV) and decaying into a charged-lepton pair (e+ e …
