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
Pixel sensors in 3D technology equip the outer ends of the staves of the Insertable B Layer (IBL), the innermost layer of the ATLAS Pixel Detector, which was installed before the start of LHC Run 2 in 2015. 3D pixel sensors are expected to exhibit more tolerance to radiation damage and are the technology of choice for the innermost layer in the ATLAS tracker upgrade for the HL-LHC programme. While
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
Feminism is a concept that can be considered extremely topical in Sweden in both the social and political context. Therefore, it is interesting to examine women’s position towards the concept and if they want to be identified as a feminist. This study is based on how women’s position towards feminism and feminists can be challenged by stereotypes and ideal types in the discourse of the concepts. T
För att kunna förstå och beskriva universum behövs det mer materia än den vi ser och kan förklara med standardmodellen för partikelfysik. Den materia som vi ser och kan ta på utgör bara en bråkdel av den materian som finns i vårt universum. Det som fattas, det som vi inte kan se men enligt observationer och beräkningar finns där, kallas mörk materia. Den kallas mörk materia då den inte reflekterarDark matter is one of our universe’s largest mysteries and very little is known about what it is. One of the dominating theories, that it originates from an early universe thermal relic, indicates that it has interaction with the Standard Model. If this is the case, dark matter can be produced at accelerators and detected indirectly by searching for missing momentum signals. LDMX will join this se
The rise of right-wing populism in Western democracies has been accompanied by a backlash against gender equality and a nostalgia for a return to traditional gender roles; a movement known as anti-feminism. The Alternative for Germany (AfD), a far-right political party in Germany, is also linked to this movement by attacking advances in gender equality and LGBTQ+ rights in its political discourse.
Våldsutvecklingen i Sverige kan spåras till de förorts- och stadsdelsbaserade gängen och den organiserade brottsligheten i landet anses vara ett av samtidens största problem. För att inte skada grundläggande värden, som demokrati och rättssäkerhet, är det nödvändigt att motverka den organiserade brottsligheten. Oaktat hur brottslig en verksamhet är, saknas det förutsättningar enligt svensk gälland
I en tid av ökande globala utmaningar är organisationer inte längre passiva åskådare till externa kriser, utan använder dem som strategiska möjligheter för positionering. Genom att avvika från traditionella kristeorier som fokuserar på interna händelser där företag är direkt involverade eller bär ansvar, undersöker denna studie hur externa kriser utnyttjas när företagens direkta inblandning är minIn an era of increasing global disruption, organizations are no longer passive observers of external crises but utilize them as strategic positioning opportunities. Departing from traditional crisis theories focused on internal incidents where companies are directly involved or bear responsibility, this study investigates the leverage of external crises where companies’ direct involvement is minim
Till följd av en allt strängare lagstiftning kring marknadsföring av tobaksfria nikotinprodukter i Sverige har varumärket Loop utvecklat nya strategier för att synas i sociala medier utan att bryta mot rådande regler. Denna studie undersöker hur Loop iscensätter och kommunicerar sin varumärkesidentitet på Instagram genom strategisk kommunikation som undviker direkt produktreklam. Med utgångspunkt In response to increasingly strict regulations surrounding the marketing of tobacco-free nicotine products in Sweden, nicotine pouch brand Loop has adopted new strategies to maintain brand visibility and consumer engagement on social media. This study examines how Loop constructs and communicates its brand identity on Instagram in a legally restricted environment, using strategic communication tha
