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 ...

This paper presents a measurement of the polarisation of τ leptons produced in Z/γ ∗ → τ τ decays which is performed with a dataset of proton—proton collisions at √s = 8 TeV, corresponding to an integrated luminosity of ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
The differential cross-section for the production of a W boson in association with a top quark is measured for several particle-level observables. The measurements are performed using 36.1 fb−1 of pp collision data collected ...

A search for charged Higgs bosons heavier than the top quark and decaying via H± → tb is presented. The data analysed corresponds to 36.1 fb−1 of pp collisions at √ s = 13 TeV and was recorded with the ATLAS detector at ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A search for doubly charged Higgs bosons with pairs of prompt, isolated, highly energetic leptons with the same electric charge is presented. The search uses a proton– proton collision data sample at a centre-of-mass energy ...

Measurements of ZZ production in the lþl−l0þl0− channel in proton–proton collisions at 13 TeV center-of-mass energy at the Large Hadron Collider are presented. The data correspond to 36.1 fb−1 of collisions collected by ...

A search for the direct production of charginos and neutralinos in final states with at least two hadronically decaying tau leptons is presented. The analysis uses a dataset of pp collisions corresponding to an integrated ...

Narrow resonances decaying into W W , W Z or Z Z boson pairs are searched for in 36.7 fb−1 of proton– proton collision data at a centre-of-mass energy of √s = 13 TeV recorded with the ATLAS detector at the Large Hadron ...
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
A search is conducted for new resonances decaying into a WW or W Z boson pair, where one W boson decays leptonically and the other W or Z boson decays hadronically. It is based on proton-proton collision data with an ...

This paper presents a direct measurement of the decay width of the top quark using tt ¯ events in the lepton+jets final state. The data sample was collected by the ATLAS detector at the LHC in proton–proton collisions at ...
