(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 supersymmetry in events with four or more charged leptons (electrons, muons and τ-leptons) is presented. The analysis uses a data sample corresponding to 139 fb−1 of proton-proton collisions delivered by the ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
A search for long-lived particles, which have come to rest within the ATLAS detector, is presented. The subsequent decays of these particles can produce high-momentum jets, resulting in large out-of-time energy deposits ...
(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, 2022)
Measurements of the production cross-sections of the Standard Model (SM) Higgs boson (H) decaying into a pair of τ-leptons are presented. The measurements use data collected with the ATLAS detector from pp collisions ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
Abstract The ATLAS experiment at the Large Hadron Collider has a broad physics programme ranging from precision measurements to direct searches for new particles and new interactions, requiring ever larger and ever more ...
