This Letter presents the measurement of differential cross sections of isolated prompt photons produced in association with a b-jet or a c-jet. These final states provide sensitivity to the heavy-flavour content of the ...

A search for exotic decays of the Higgs boson into a pair of spin-zero particles, H → aa, where the a-boson decays into b-quarks promptly or with a mean proper lifetime cτa up to 6 mm and has a mass in the range of 20–60 ...

A search for new phenomena in final states containing an e+e− or μ+μ− pair, jets, and large missing transverse momentum is presented. This analysis makes use of proton–proton collision data with an integrated luminosity ...

A search for the supersymmetric partners of quarks and gluons (squarks and gluinos) in final states containing hadronic jets and missing transverse momentum, but no electrons or muons, is presented. The data used in this ...

A search for long-lived, massive particles predicted by many theories beyond the Standard Model is presented. The search targets final states with large missing transverse momentum and at least one highmass displaced vertex ...

Measurements are made of differential cross-sections of highly boosted pair-produced top quarks as a function of top-quark and t¯t system kinematic observables using proton-proton collisions at a center-ofmass energy of ...

A search for pair production of up-type vector-like quarks (T) with a significant branching ratio into a top quark and either a Standard Model Higgs boson or a Z boson is presented. The same analysis is also used to search ...

The coupling properties of the Higgs boson are studied in the four-lepton (e, µ) decay channel using 36.1 fb−1 of pp collision data from the LHC at a centre-of-mass energy of 13 TeV collected by the ATLAS detector. Cross ...

A search for W -boson production in the W → t¯ b → qq¯ b¯ b decay channel is presented using 36.1 fb−1 of 13 TeV proton–proton collision data collected by the ATLAS detector at the Large Hadron Collider in 2015 and 2016. ...

A search for the narrow structure, Xð5568Þ, reported by the D0 Collaboration in the decay sequence X → B0 sπ , B0 s → J=ψϕ, is presented. The analysis is based on a data sample recorded with the ATLAS detector at the LHC ...
