A search for a hypothetical heavy scalar particle, X, decaying into a singlet scalar particle, S, and a Standard Model Higgs boson, H, using 140 fb−1 of proton-proton collision data at the centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the LHC is presented. The explored mass range is 300 ≤ mX ≤ 1000 GeV and 170 ≤ mS ≤ 500 GeV. The signature of this search is one or two leptons
This report reviews the published results of searches for possible additional scalar particles and exotic decays of the Higgs boson performed by the ATLAS Collaboration using up to 140 fb−1 of 13 TeV proton–proton collision data collected during Run 2 of the Large Hadron Collider. Key results are examined, and observed excesses, while never statistically compelling, are noted. Constraints are plac
This Letter presents a differential cross-section measurement of Lund subjet multiplicities, suitable for testing current and future parton shower Monte Carlo algorithms. This measurement is made in dijet events in 140 fb−1 of s=13 TeV proton–proton collision data collected with the ATLAS detector at CERN's Large Hadron Collider. The data are unfolded to account for acceptance and detector-related
In the present work, we addressed the relationship between parental leave policies and social norms. Using a pre-registered, cross-national approach, we examined the relationship between parental leave policies and the perception of social norms for the gender division of childcare. In this study, 19,259 students (11,924 women) from 48 countries indicated the degree to which they believe childcare
This paper presents a search for a new Z′ resonance decaying into a pair of dark quarks which hadronise into dark hadrons before promptly decaying back as Standard Model particles. This analysis is based on proton-proton collision data recorded at s = 13 TeV with the ATLAS detector at the Large Hadron Collider between 2015 and 2018, corresponding to an integrated luminosity of 139 fb−1. After sele
Research aimThis paper examines place brand communication in marginalised urban areascharacterised by low levels of attractiveness to residents, visitors and investment. Most previous research on marginalised places has focused on issues such as crime prevention and securitydevelopment, rather than on branding and attractiveness. The aim of this research is to explore the roleof place branding eff
High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [(Formula presented)]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a ch
The two-particle momentum correlation functions between charm mesons (D∗± and D±) and charged light-flavor mesons (π± and K±) in all charge combinations are measured for the first time by the ALICE Collaboration in high-multiplicity proton-proton collisions at a center-of-mass energy of s=13 TeV. For DK and D∗K pairs, the experimental results are in agreement with theoretical predictions of the re
Stormwater management is essential for preventing urban flooding and protecting water quality in receiving bodies. Traditionally viewed as a nuisance, stormwater is now being re-evaluated as an alternative resource for non-potable uses such as toilet flushing and irrigation through rainwater harvesting systems (RWHS). Within the European Union's Horizon 2020 project REWAISE, pilot studies with cer
Background: The potential of generative artificial intelligence (genAI) tools, such as ChatGPT, is being increasingly explored in healthcare settings. However, the same tools also introduce significant cybersecurity risks that could compromise patient safety, data integrity, and institutional trust. This study aimed to examine real-world security breaches involving genAI and extrapolate their pote
ESS, a European Research Infrastructure Consortium (ERIC), is getting ready to be a leading multidisciplinary facility with the world's most potent neutron source. Dedicated to scientific breakthroughs, ESS focuses on materials, energy, health, and environmental research to address key societal challenges. ESS will host 22 specialized scientific instruments selected to cover a broad range of exper
The CP properties of the coupling between the Higgs boson and the top quark are investigated using 139 fb−1 of proton–proton collision data recorded by the ATLAS experiment at the LHC at a centre-of-mass energy of s=13 TeV. The CP structure of the top quark–Higgs boson Yukawa coupling is probed in events with a Higgs boson decaying into a pair of b-quarks and produced in association with either a
ATLAS measured the centrality dependence of the dijet yield using Formula Presented of Formula Presented data collected at Formula Presented in 2016. The event centrality, which reflects the Formula Presented impact parameter, is characterized by the total transverse energy registered in the Pb-going side of the forward calorimeter. The central-to-peripheral ratio of the scaled dijet yields, Formu
The 7th International Workshop on Virtual, Augmented, and Mixed Reality for Human-Robot Interaction (VAM-HRI) seeks to bring together researchers from human-robot interaction (HRI), robotics, and mixed reality (MR) to address the challenges related to mixed reality interactions between humans and robots. Key topics include the development of robots capable of interacting with humans in mixed reali
An amplitude analysis of the B0→K∗0μ+μ- decay is presented. The analysis is based on data collected by the LHCb experiment from proton-proton collisions at s=7, 8 and 13 TeV, corresponding to an integrated luminosity of 4.7 fb-1. For the first time, Wilson coefficients and nonlocal hadronic contributions are accessed directly from the unbinned data, where the latter are parametrized as a function
Flow harmonic coefficients, vn, which are the key to studying the hydrodynamics of the quark-gluon plasma (QGP) created in heavy-ion collisions, have been measured in various collision systems and kinematic regions and using various particle species. The study of flow harmonics in a wide pseudorapidity range is particularly valuable to understand the temperature dependence of the shear viscosity t
What is sound when it is not heard? How does this unheard sound affect us? What might such sound reveal to us and how would we know? How do we recall sounds when their sources are no longer accessible? Traces of Sound. Reflections of Sounds Unheard invites scholars of music archae-ology, German literature, media technology, sound art, human perception and theoretical physics to reflect u
The peacekeeping mission in the Democratic Republic of Congo (DRC) is one of the most extensive and complex missions ever carried out by the United Nations. Amongst the operational adaptation, one challenge has remained consistent; the crisis of Sexual Exploitation and Abuse (SEA) committed by UN peacekeepers against the very civilians they are mandated to protect. This essay aims to explain how t
Bakgrund Att få ett barn med medfött hjärtfel är en omvälvande och ofta chockartad upplevelse för föräldrar, där särskilt pappor kan känna sig osynliggjorda och sakna anpassat stöd, samtidigt som deras behov och reaktioner ofta skiljer sig från mammors. Syftet med denna studie var att undersöka pappors erfarenheter av socialt stöd när ett barn föds med hjärtfel i Sverige. Metod Studien genomfördes
