This Letter presents a constraint on the total width of the Higgs boson (ΓH) using a combined measurement of on-shell Higgs boson production and the production of four top quarks, which involves contributions from off-shell Higgs boson-mediated processes. This method relies on the assumption that the tree-level Higgs-top Yukawa coupling strength is the same for on-shell and off-shell Higgs boson p
Comprehensive Sexuality Education (CSE) is central to promoting adolescents’ sexual health and rights. In Sweden, CSE is now referred to as Sexuality, Consent and Relationships (SCR) education, following a curriculum revision in 2022. This study explored how upper secondary school students (aged 16–19) experienced SCR education. A digital questionnaire was completed in the classroom by 1378 studen
A search for the production of three massive vector bosons, VVZ(V=W,Z), in proton–proton collisions at s=13 TeV is performed using data with an integrated luminosity of 140 fb−1 recorded by the ATLAS detector at the Large Hadron Collider. Events produced in the leptonic final states WWZ→ℓνℓνℓℓ (ℓ=e,μ), WZZ→ℓνℓℓℓℓ, ZZZ→ℓℓℓℓℓℓ, and the semileptonic final states WWZ→qqℓνℓℓ and WZZ→ℓνqqℓℓ, are analyse
In 2022 and 2023, the Large Hadron Collider produced approximately two billion hadronic interactions each second from bunches of protons that collide at a rate of 40 MHz. The ATLAS trigger system is used to reduce this rate to a few kHz for recording. Selections based on hadronic jets, their energy, and event topology reduce the rate to Ô(10) kHz while maintaining high efficiencies for important s
The years 2023 and 2024 were characterized by unprecedented warming across the globe, underscoring the urgency of climate action. Robust science advice for decision makers on subjects as complex as climate change requires deep cross- and interdisciplinary understanding. However, navigating the ever-expanding and diverse peer-reviewed literature on climate change is enormously challenging for indiv
Correlations among conserved quantum numbers, such as the net-electric charge, the net-baryon, and the net-strangeness in heavy-ion collisions, are crucial for exploring the QCD phase diagram. In this paper, these correlations are investigated using net-proton number (as a proxy for the net-baryon), net-kaon number (for the net-strangeness), and net-charged particle number in Pb-Pb collisions at =
ATLAS, a general-purpose experiment at the Large Hadron Collider (LHC), makes use of a large internationally-distributed computing infrastructure, including over 106 TB of managed data on disk and tape and almost one million simultaneously running CPU cores. Upgrades for the High-Luminosity LHC (HL-LHC) will increase the required computing resources by a factor of 3–4 by the beginning of the 2030s
Higgs boson production cross-sections via gluon–gluon fusion and vector-boson fusion in proton–proton collisions are measured in the H→WW∗→ℓνℓν decay channel. The Large Hadron Collider delivered proton–proton collisions at a centre-of-mass energy of 13TeV between 2015 and 2018, which were recorded by the ATLAS detector, corresponding to an integrated luminosity of 140fb-1. The total cross-sections
A search for exotic decays of the Higgs boson H into new scalar or pseudoscalar particles that subsequently decay into b-quarks is presented. The search considers ZH production with several decay scenarios for the Higgs boson; first to a pair of identical scalars, H → 2a → 4b, second to a pair of scalars with different masses (ma1 < ma2), either directly, H → a1a2 → 4b, or via a longer decay chain
A search for R-parity-conserving supersymmetry in events with large missing transverse momentum, jets and at least one hadronically decaying τ-lepton is presented. Both gluino and squark pair production are considered, with the cascade decay of each gluino or squark producing either a τ-slepton or a τ-sneutrino. Three channels are examined, requiring either exactly one hadronically decaying τ-lept
This thesis examines the discursive mechanisms through which prominent technology founders mobilise entrepreneurial identity to construct and legitimise visions of political governance in their public discourse. Drawing on Faircloughian Critical Discourse Analysis and the concept of ideological entrepreneurship, the study analyses a corpus of public texts produced by Peter Thiel and Elon Musk betw
Unga vuxnas skuldbelopp ökar i Sverige, samtidigt som ett växande forskningsfält visar att skuldsättning är förknippad med psykisk ohälsa. Syftet med denna tvärsnittsstudie var att undersöka prevalensen av snabblåneskulder bland unga vuxna, samt att identifiera livshändelser som föregick att snabblånet togs. Därutöver var syftet att undersöka sambandet mellan skulder från snabblån, psykisk ohälsa,Young adults’ debts are increasing in Sweden, while a growing body of research shows that indebtedness is associated with psychological distress. The aim of this cross-sectional study was to examine the prevalence of debt from payday loans among young adults, as well as to identify life-course events that preceded taking on such loans. In addition, the study aimed to investigate the association wi
This thesis examines the relationship between the Green Asset Ratio (GAR) and banks’ market-based funding costs in the European banking sector. The GAR is a sustainability disclosure introduced under the EU Taxonomy framework and is intended to provide a more standardized measure of banks’ environmentally sustainable exposures than traditional ESG ratings.
