A search for the production of top-quark pairs with the same electric charge (tt or tt¯) is presented. The analysis uses proton-proton collision data at s = 13 TeV, recorded by the ATLAS detector at the Large Hadron Collider, corresponding to an integrated luminosity of 140 fb−1. Events with two same-charge leptons and at least two b-tagged jets are selected. Neural networks are employed to define
A search for the production of a Higgs boson and one or more charm quarks, in which the Higgs boson decays into a photon pair, is presented. This search uses proton-proton collision data with a centre-of-mass energy of s = 13 TeV and an integrated luminosity of 140 fb−1 recorded by the ATLAS detector at the Large Hadron Collider. The analysis relies on the identification of charm-quark-containing
There is limited research examining the perspectives on the use of genetic testing in psychiatric care among individuals of non-European ancestry. Adults with obsessive–compulsive disorder (OCD) of Latin American ancestry (n = 1,513) completed a survey assessing their interest in receiving genetic testing for OCD, their level of comfort with disclosing this information, views on the use of genetic
We present the first forward-rapidity measurements of elliptic anisotropy of open-heavy-flavor muons at the Relativistic Heavy Ion Collider. The measurements are based on data samples of Au + Au collisions at √ sNN = 200GeV collected by the PHENIX experiment in 2014 and 2016 with integrated luminosity of 14.5nb−1. The measurements are performed in the pseudorapidity range 1.2 < |η| < 2 and cover t
The PHENIX experiment at the Relativistic Heavy Ion Collider has measured low-mass vector-meson (ω + ρ and φ) production through the dimuon decay channel at forward rapidity (1.2 < |y| < 2.2) in p + p and Au + Au collisions at √sNN = 200 GeV. The low-mass vector-meson yield and nuclear-modification factor were measured as a function of the average number of participating nucleons, ‹Npart›, and the
The coherent J/ ψ photoproduction cross section is measured for the first time at midrapidity in peripheral to semicentral Pb−Pb collisions at sNN=5.02 TeV. The centrality differential cross section d σ /d y is reported for the centrality range 40–90%, together with the doubly-differential cross section d2 σ /d y d p T, extracted in two peripheral centrality classes. The J/ ψ mesons are reconstruc
A calibration of the ATLAS flavour-tagging algorithms using a new calibration procedure based on optimal transportation maps is presented. Simultaneous, continuous corrections to the b-jet, c-jet, and light-flavour jet classification probabilities from jet-tagging algorithms in simulation are derived for b-jets using tt¯→eμννbb data. After application of the derived calibration maps, closure betwe

A search for a light charged Higgs boson produced in decays of the top quark, t→H±b with H±→cs, is presented. This search targets the production of top-quark pairs tt¯→WbH±b, with W→ℓν (ℓ=e,μ), resulting in a lepton-plus-jets final state characterised by an isolated electron or muon and at least four jets. The search exploits b-quark and c-quark identification techniques as well as multivariate me
22 April 2026 17:00 to 26 April 2026 20:00 | Concert, Other Welcome to a new edition of INTONAL Festival at IAC! For the 2026 edition, we have shaped a curatorial framework that brings together our 15-years tradition of acousmonium practice and a focus on South and Central American sound scenes. This perspective unfolds through a dedicated talk and curated concerts, with music spatialized live on

The purpose of this study was to examine the development of contemporary psychedelic discourse through well-defined problem statements and proposed solutions. The study explored the construction of psychedelics as a psychiatric critique, an effective and natural approach to treating mental illness, and as a method for self-improvement and self-optimization. A discourse analysis was conducted of th
The Arctic Council has long been portrayed as an arena for stable and depoliticized cooperation, often referred to as exemplifying the idea of Arctic exceptionalism. Russia’s full-scale invasion of Ukraine in 2022, and the following pause in cooperation, did however raise questions about the resilience of the cooperation in the council. This paper presents a discourse analysis of ministerial meeti
This thesis examens lobbying strategies by corporations within the context of the European Union’s regulatory framework. The example used is fast fashion company Shein, who is affected by EU legislation as they enter the EU market. The research focuses on access points and constraints when corporations lobby the EU and explain why Shein won’t be successful. Evidence collected through Process Trac
Extreme heat is not neutral. In Athens, the dense urban environment and harsh summer climate disproportionately impact the socio-economically marginalized. This research bridges the gap between climate data and human experience by uniting geospatial and qualitative survey data regarding heatwaves in Athens Municipality, with urban heat island research, vulnerability theory and climate justice.
