(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
Measurements of the Standard Model Higgs boson decaying into a bb¯ pair and produced in association with a W or Z boson decaying into leptons, using proton–proton collision data collected between 2015 and 2018 by the ATLAS ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
A search for the supersymmetric partners of quarks and gluons (squarks and gluinos) in final states containing jets and missing transverse momentum, but no electrons or muons, is presented. The data used in this search ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
The yield of charged particles opposite to a Z boson with large transverse momentum (pT) is measured in 260 pb−1 of pp and 1.7 nb−1 of Pb+Pb collision data at 5.02 TeV per nucleon pair recorded with the ATLAS detector ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
A search for the pair production of heavy leptons as predicted by the type-III seesaw mechanism is presented. The search uses proton–proton collision data at a centre-of-mass energy of 13 TeV, corresponding to 139fb−1 of ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
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±W∓ or ZZ pairs from a decay of a dark ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
A search for new phenomena in final states with hadronically decaying tau leptons, b-jets, and missing transverse momentum is presented. The analyzed dataset comprises pp collision data at a center-of-mass energy of ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
A search for charginos and neutralinos at the Large Hadron Collider using fully hadronic final states and missing transverse momentum is reported. Pair-produced charginos or neutralinos are explored, each decaying into a ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
A novel search for exotic decays of the Higgs boson into pairs of long-lived neutral particles, each decaying into a bottom quark pair, is performed using 139 fb−1 of s√ = 13 TeV proton-proton collision data collected with ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
The fragmentation properties of jets containing b-hadrons are studied using charged B mesons in 139 fb−1 of pp collisions at s√ = 13 TeV, recorded with the ATLAS detector at the LHC during the period from 2015 to 2018. The ...
