Search for dark matter in events with missing transverse momentum and a Higgs boson decaying into two photons in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2021
A search for dark-matter particles in events with large missing transverse momentum and a Higgs boson candidate decaying into two photons is reported. The search uses 139 fb −1 of proton-proton collision data collected at s $$ \sqrt{s} $$ = 13 TeV with ...

Performance of the missing transverse momentum triggers for the ATLAS detector during Run-2 data taking

open access: yesJournal of High Energy Physics, 2020
The factor of four increase in the LHC luminosity, from 0.5 × 1034 cm −2s −1 to 2.0 × 1034cm −2s −1, and the corresponding increase in pile-up collisions during the 2015–2018 data-taking period, presented a challenge for the ATLAS trigger, particularly ...

Production of light (anti)nuclei in pp collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics, 2022
Understanding the production mechanism of light (anti)nuclei is one of the key challenges of nuclear physics and has important consequences for astrophysics, since it provides an input for indirect dark-matter searches in space. In this paper, the latest

Measurement of the Z γ → ν ν ¯ γ $$ Z\gamma \to \nu \overline{\nu}\gamma $$ production cross section in pp collisions at s = 13 $$ \sqrt{s}=13 $$ TeV with the ATLAS detector and limits on anomalous triple gauge-boson couplings

open access: yesJournal of High Energy Physics, 2018
The production of Z bosons in association with a high-energy photon (Zγ production) is studied in the neutrino decay channel of the Z boson using pp collisions at s = 13 $$ \sqrt{s}=13 $$ TeV. The analysis uses a data sample with an integrated luminosity

Search for direct production of electroweakinos in final states with missing transverse momentum and a Higgs boson decaying into photons in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2020
A search for a chargino-neutralino pair decaying via the 125 GeV Higgs boson into photons is presented. The study is based on the data collected between 2015 and 2018 with the ATLAS detector at the LHC, corresponding to an integrated luminosity of 139 fb

Measurement of the Drell-Yan triple-differential cross section in pp collisions at s=8 $$ \sqrt{s}=8 $$ TeV

open access: yesJournal of High Energy Physics, 2017
This paper presents a measurement of the triple-differential cross section for the Drell-Yan process Z/γ * → ℓ + ℓ − where ℓ is an electron or a muon. The measurement is performed for invariant masses of the lepton pairs, m ℓℓ , between 46 and 200 GeV ...

An Updated Description of Heavy-Hadron Interactions in Geant-4 [PDF]

open access: yes, 2009
Exotic stable massive particles (SMP) are proposed in a number of scenarios of physics beyond the Standard Model. It is important that LHC experiments are able both to detect and extract the quantum numbers of any SMP with masses around the TeV scale. To

Searches for third-generation scalar leptoquarks in s $$ \sqrt{s} $$ = 13 TeV pp collisions with the ATLAS detector

open access: yesJournal of High Energy Physics, 2019
Limits are set on the pair production of scalar leptoquarks, where all possible decays of the leptoquark into a quark (t, b) and a lepton (τ, ν) of the third generation are considered. The limits are presented as a function of the leptoquark mass and the
