The production yields of the Σ(1385)± and Ξ(1530)0 resonances are measured in pp collisions at s = 13 TeV with ALICE. The measurements are performed as a function of the charged-particle multiplicity ⟨dNch/dη⟩, which is related to the energy density produced in the collision. The results include transverse momentum (pT) distributions, pT-integrated yields, mean transverse momenta of Σ(1385)± and Ξ

In the context of a geological repository for nuclear waste, fast and accurate predictions of decay heat are needed for different applications ranging from canister loading optimization to comparing decay heat predictions from state-of-the-art codes with experimental measurements. This work uses a large database of simulated pressurized water reactor (PWR) spent nuclear fuel (SNF) with an extensiv

After a long period of being constructed as anonymous administration complexes, first instance courts are once again being built as emblematic elements of the city, designed by renowned architects and rising up on central plots adjacent to train stations, headquarter buildings and exclusive residential areas. This is happening at a time of centralisation, upsizing and property privatisation, and w

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

Collective action is a powerful tool for social change and is fundamental to women and girls’ empowerment on a societal level. Collective action towards gender equality could be understood as intentional and conscious civic behaviors focused on social transformation, questioning power relations, and promoting gender equality through collective efforts. Various instruments to measure collective act

Deuterons are atomic nuclei composed of a neutron and a proton held together by the strong interaction. Unbound ensembles composed of a deuteron and a third nucleon have been investigated in the past using scattering experiments, and they constitute a fundamental reference in nuclear physics to constrain nuclear interactions and the properties of nuclei. In this work, K+-d and p-d femtoscopic corr

The observation of the electroweak production of a W boson and a photon in association with two jets, using pp collision data at the Large Hadron Collider at a centre of mass energy of s=13 TeV, is reported. The data were recorded by the ATLAS experiment from 2015 to 2018 and correspond to an integrated luminosity of 140 fb-1. This process is sensitive to the quartic gauge boson couplings via the

We propose and study a weakly convergent variant of the forward-backward algorithm for solving structured monotone inclusion problems. Our algorithm features a per-iteration deviation vector, providing additional degrees of freedom. The only requirement on the deviation vector to guarantee convergence is that its norm is bounded by a quantity that can be computed online. This approach offers great

This Letter presents the first study of Higgs boson production in association with a vector boson (V ¼ W or Z) in the fully hadronic qqbb final state using data recorded by the ATLAS detector at the LHC in proton-proton collisions at √s = 13 TeV and corresponding to an integrated luminosity of 137 fb−1. The vector bosons and Higgs bosons are each reconstructed as large-radius jets and tagged using

A search for the decay of the Higgs boson to a Z boson and a light, pseudoscalar particle, a, decaying respectively to two leptons and to two photons is reported. The search uses the full LHC Run 2 proton–proton collision data at s=13 TeV, corresponding to 139 fb−1 collected by the ATLAS detector. This is one of the first searches for this specific decay mode of the Higgs boson, and it probes unex

Within the upcoming decade many countries have the ambition of banning the sale of new cars that emit carbon dioxide in order to reduce greenhouse gas emissions from the transport sector. Electric cars have been established as a key solution to combat climate change by replacing traditional internal combustion engine (ICE) vehicles which are being banned. To support the transition from ICE vehicle

The purpose of this thesis was to outline the normative structure and regulation of emotional expressions, i.e. the emotional regime, for young people concerning climate change. Climate change is a global issue implying several challenges for social workers, such as individuals experiencing emotional distress, which young people have been emphasized as especially vulnerable to. Youths’ abilities t

This study aimed to identify which perpetrators appear in the culture of honor and how their roles are described in four women's depictions in their autobiographies. Furthermore, the aim was to understand the upholding of the culture of honor through their stories. The chosen method for this study was a qualitative thematic text analysis of four autobiographies. The theoretical framework for t

Increasing demands for the green transition have created an ethical dilemma: How can the extraction of critical minerals be combined with protection of Indigenous rights and local ecosystems? Is it even possible to find solutions to the conflicts that emerge in “green” energy projects? Contributing to these debates, this thesis set out to answer the following question: How can we understand pro- a

This study examines the determinants of player salaries in Europe’s top five men’s football leagues (Premier League, La Liga, Serie A, Bundesliga, Ligue 1), focusing on the impact of player representation models for forward players. We compare players represented by football agencies versus those represented by relatives, and explore whether agency size affects salaries. Drawing on principal-agent
