Several extensions of the standard model predict associated production of dark-matter particles with a Higgs boson. Such processes are searched for in final states with missing transverse momentum and a Higgs boson decaying to a bb pair with the ATLAS detector using 36.1 fb-1 of pp collisions at a center-of-mass energy of 13 TeV at the LHC. The observed data are in agreement with the standard mode
A search for heavy right-handed Majorana or Dirac neutrinos N R and heavy right-handed gauge bosons W R is performed in events with a pair of energetic electrons or muons, with the same or opposite electric charge, and two energetic jets. The events are selected from pp collision data with an integrated luminosity of 36.1 fb −1 collected by the ATLAS detector at s=13 TeV. No significant deviations
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 were recorded by the ATLAS experiment in proton-proton collisions at a centre-of-mass energy of s = 13 TeV during Run 2 of the Large Hadron Collider, corresponding to an integrated
Horizon Europe has identified climate-neutral and smart cities as one of its mission areas. In Sweden, the national innovation programme Viable Cities has set its sights on realising climate neutrality in cities by 2030. In both cases, a mission-oriented approach focused on citizens as drivers of climate action represents a pathway to success. However, citizen involvement has been presented as an
Popular Abstract in Swedish Eftersom allt i och runt oss består av kemikalier är det av högsta vikt att vi förstår hur dessa reagerar med varandra. Katalytiska omvandlingar är kemiska reaktioner där en katalysator underhåller en reaktion utan att själv förbrukas. Inom metallorganisk kemi är tillverkning och förstålelsen av hur komplex med övergångsmetaller kan användas vi katalys mycket viktig. KoAbstract The work presented in this thesis discusses synthesis of PCP-complexes and utilisations of such organometallic compounds in catalysis. The complexes, obtained by intramolecular Csp3-H activation, are based on the metals palladium, platinum and iridium. The synthesis of PCP-ligands include new and improved preparative routes to the previously known cis-1,3-bis-(di-iso-propylphosphinito)cy
A search for production of supersymmetric particles in final states containing jets, missing transverse momentum, and at least one hadronically decaying tau lepton is presented. The data were recorded by the ATLAS experiment in root s = 7 TeV proton-proton collisions at the Large Hadron Collider. No excess above the Standard Model background expectation was observed in 2.05 fb(-1) of data. The res
A search for Higgs boson decays to invisible particles is performed using 20.3 [Formula: see text] of pp collision data at a centre-of-mass energy of 8 TeV recorded by the ATLAS detector at the Large Hadron Collider. The process considered is Higgs boson production in association with a vector boson ([Formula: see text] or Z) that decays hadronically, resulting in events with two or more jets and
Migration has been a contested issue in Swedish politics over the past decade, and media coverage has repeatedly sparked debate about the impartiality of Sveriges Television (SVT). Using large language models (LLMs) as coding instruments, this study examines how migration has been framed in SVT Nyheter, a major Swedish public service news outlet, between 2014 and 2024. Rather than explaining causa
This study investigates the factors influencing the adoption and acceptance of cloud-based solutions within organizational contexts, emphasizing the strategic insights necessary for effective cloud migration. Cloud computing, marked by its scalability, has significantly transformed information technology landscapes. However, the adoption rates vary widely across industries, driven by diverse organ
This thesis aims to evaluate the extent to which income from embedded royalties in mixed contracts generated by a subsidiary falling under the ATAD’s CFC rules can be attributed to the tax base of the parent company as “any other income generated from intellectual property” as established by Article 7(2)(a)(ii) ATAD in light of the freedom of establishment under Article 49 TFEU. First, it explains
A search for supersymmetry targeting the direct production of winos and higgsinos is conducted in final states with either two leptons (e or μ) with the same electric charge, or three leptons. The analysis uses 139 fb−1 of pp collision data at (Formula presented.) TeV collected with the ATLAS detector during Run 2 of the Large Hadron Collider. No significant excess over the Standard Model expectat

Charged Higgs bosons produced either in top-quark decays or in association with a top quark, subsequently decaying via (Formula presented), are searched for in (Formula presented) of proton-proton collision data at (Formula presented) recorded with the ATLAS detector. Depending on whether the top quark is produced together with the (Formula presented) decays hadronically or semileptonically, the s
Objective Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a rare disease that can result in severe bleeding in a fetus or newborn, including intracranial hemorrhage. Maternal-fetal human platelet antigen (HPA)-1a incompatibility is a prerequisite to maternal HPA-1a alloimmunization, which may result in FNAIT. The risk of HPA-1a alloimmunization is approximately 25-times higher in HPA-1
