Measurements of inclusive, differential cross-sections for the production of events with missing transverse momentum in association with jets in proton-proton collisions at $ \sqrt{s} $ = 13 TeV are presented. The measurements are made with the ATLAS detector using an integrated luminosity of 140 fb$^{−1}$ and include measurements of dijet distributions in a region in which vector-boson fusion processes are enhanced [...]

A measurement of the production of W bosons with opposite electric charges in association with two jets is presented based on 140 fb$^{−1}$ of data collected by the ATLAS detector in proton-proton collisions at $ \sqrt{s} $ = 13 TeV. The analysis is sensitive to the scattering of W bosons, which is of particular interest in the ATLAS physics programme as it can be used to probe the electroweak symmetry breaking mechanism of the Standard Model [...]

A combination of searches for Higgs boson decays into a visible photon and a massless dark photon (H → γγ$_{d}$) is presented using 139 fb$^{−1}$ of proton-proton collision data at a centre-of-mass energy of $ \sqrt{s} $ = 13 TeV recorded by the ATLAS detector at the Large Hadron Collider. The observed (expected) 95% confidence level upper limit on the Standard Model Higgs boson decay branching ratio is determined to be $ \mathcal{B} $(H → γγ$_{d}$) < 1.3% (1.5)% [...]

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 with the ATLAS detector. At 95% confidence level (CL), the upper limit on the production rate is 2.9 times the standard model (SM) prediction, with an expected limit of 2.4 assuming no Higgs boson pair production. [...]

Differential cross-sections for top-quark pair production, inclusively and in association with jets, are measured in pp collisions at a centre-of-mass energy of 13 TeV with the ATLAS detector at the LHC using an integrated luminosity of 140 fb$^{−1}$. The events are selected with one charged lepton (electron or muon) and at least four jets [...]

World of the channeling effect

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 decays into leptons and the other into hadrons. [...]

A search is presented for non-resonant Higgs boson pair production, targeting the bbZZ, 4V (V = W or Z), VVττ, 4τ, γγVV and γγττ decay channels. Events are categorised based on the multiplicity of light charged leptons (electrons or muons), hadronically decaying tau leptons, and photons [...]

A search for dark mesons originating from strongly-coupled, SU(2) dark flavor symmetry conserving models and decaying gaugephobically to pure Standard Model final states containing top and bottom quarks is presented. The search targets fully hadronic final states and final states with exactly one electron or muon and multiple jets [...]
