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
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
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
Human dignity is a key foundational value for human rights. Human rights are however facing new challenges from the development and deployment of artificial intelligence technologies in society. Governance efforts to address such challenges have encompassed drawing up ethical guidelines, policy measures as well as legal regulation. The world’s first comprehensive regulation on artificial intellige
The identification of jets originating from quarks and gluons, often referred to as quark/gluon tagging, plays an important role in various analyses performed at the Large Hadron Collider, as Standard Model measurements and searches for new particles decaying to quarks often rely on suppressing a large gluon-induced background. This paper describes the measurement of the efficiencies of quark/gluo
Measurements of inclusive and differential production cross-sections of a top-quark-top-antiquark pair in association with a W boson (tt¯W) are presented. They are performed by targeting final states with two same-sign or three isolated leptons (electrons or muons) and are based on s = 13 TeV proton-proton collision data with an integrated luminosity of 140 fb−1, recorded from 2015 to 2018 with th
Three searches for the direct production of τ-sleptons or charginos and neutralinos in final states with at least two hadronically decaying τ-leptons are presented. For chargino and neutralino production, decays via intermediate τ-sleptons or W and h bosons are considered. The analysis uses a dataset of pp collisions corresponding to an integrated luminosity of 139 fb−1, recorded with the ATLAS de
Long- and short-range correlations for pairs of charged particles are studied via two-particle angular correlations in pp collisions at s = 13 TeV and p–Pb collisions at sNN = 5.02 TeV. The correlation functions are measured as a function of relative azimuthal angle ∆φ and pseudorapidity separation ∆η for pairs of primary charged particles within the pseudorapidity interval |η| < 0.9 and the trans
In 1974, amidst a hunger strike by undocumented workers in Paris, the Movement of Arab Workers created a singular political action: presenting a candidate for the imminent presidential elections. They chose a member of their Al Assifa theatre group, an 18-year-old Tunisian hunger striker using the pseudonym Djellali Kamal. The campaign was conceived as a public performance highlighting the denial
The four decays, Λb0→ςc(∗)++D(∗)-K-, are observed for the first time using proton-proton collision data collected with the LHCb detector at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 6 fb-1. By considering the Λb0→Λc+D¯0K- decay as reference channel, the following branching fraction ratios are measured to be B(Λb0→ςc++D-K-)B(Λb0→Λc+D¯0K-)=0.282±0.016±0.016±0.00
Simultaneous sound event localization and detection (SELD) for multi-source sound events is an open research field. The Multi-ACCDOA format is a popular way to handle activity-coupled sound events where the same class occurs at multiple locations at the same time. An important part is the Auxiliary Duplicating Permutation Invariant Training (ADPIT) paradigm that calculates the loss for order-agnos
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
The identification of top quark decays where the top quark has a large momentum transverse to the beam axis, known as top tagging, is a crucial component in many measurements of Standard Model processes and searches for beyond the Standard Model physics at the Large Hadron Collider. Machine learning techniques have improved the performance of top tagging algorithms, but the size of the systematic
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
In the last decade, the idea of total defence – a whole-of-society approach integrating civilian and military capabilities – has gained renewed prominence in Europe, including within the European Union (EU). Concurrently, the concept of strategic autonomy – the EU’s ability to act independently – has emerged as a central feature in its security policy, driving ambitions for ‘a quantum leap forwardIn the last decade, the idea of total defence – a whole-of-society approach integrating civilian and military capabilities – has gained renewed prominence in Europe, including within the European Union (EU).
