A search for the production of three Higgs bosons ((Formula presented)) in the (Formula presented) final state is presented. The search uses (Formula presented) of proton-proton collision data at (Formula presented) collected with the ATLAS detector at the Large Hadron Collider. The analysis targets both nonresonant and resonant production of (Formula presented). The resonant interpretations prima
A search for a dark photon, a new light neutral particle, which decays promptly into collimated pairs of electrons or muons is presented. The search targets dark photons resulting from the exotic decay of the Standard Model Higgs boson, assuming its production via the dominant gluon-gluon fusion mode. The analysis is based on 140fb-1 of data collected with the ATLAS detector at the Large Hadron Co
Psychiatric disorders are highly heritable and polygenic, influenced by environmental factors and often comorbid. Large-scale genome-wide association studies (GWASs) through consortium efforts have identified genetic risk loci and revealed the underlying biology of psychiatric disorders and traits. However, over 85% of psychiatric GWAS participants are of European ancestry, limiting the applicabil
A search is conducted for a new scalar boson S, with a mass distinct from that of the Higgs boson, decaying promptly into four leptons (ℓ=e, μ) via an intermediate state containing two on-shell, promptly decaying new spin-1 bosons Zd: S→ZdZd→4ℓ, where the Zd boson has a mass between 15 and 300 GeV, and the S boson has a mass between either 30 and 115 GeV or 130 and 800 GeV. The search uses proton–
Antibiotic resistance poses a significant threat to human health, and wastewater treatment plants (WWTPs) are important reservoirs of antibiotic resistance genes (ARGs). Here, we analyze the antibiotic resistomes of 226 activated sludge samples from 142 WWTPs across six continents, using a consistent pipeline for sample collection, DNA sequencing and analysis. We find that ARGs are diverse and sim
Congenital anomalies of the kidneys and urinary tract (CAKUT) are developmental disorders that commonly cause pediatric chronic kidney disease and mortality. We examine here rare coding variants in 248 CAKUT trios and 1742 singleton CAKUT cases and compare them to 22,258 controls. Diagnostic and candidate diagnostic variants are detected in 14.1% of cases. We find a significant enrichment of rare
Measurements of jet substructure are key to probing the energy frontier at colliders, and many of them use track-based observables which take advantage of the angular precision of tracking detectors. Theoretical calculations of track-based observables require ‘track functions’, which characterize the transverse momentum fraction rq carried by charged hadrons from a fragmenting quark or gluon. This
The mass of the top quark is measured using top-quark-top-antiquark pair events with high transverse momentum top quarks. The dataset, collected with the ATLAS detector in proton–proton collisions at s=13 TeV delivered by the Large Hadron Collider, corresponds to an integrated luminosity of 140 fb−1. The analysis targets events in the lepton-plus-jets decay channel, with an electron or muon from a
A measurement of the B0 meson lifetime using B0→J/ψK∗0 decays in data from 13 TeV proton–proton collisions with an integrated luminosity of 140fb-1 recorded by the ATLAS detector at the LHC is presented. The measured effective lifetime is (Formula presented.) The average decay width extracted from the effective lifetime, using parameters from external sources, is (Formula presented.) where the unc
The pT-differential cross section of ω meson production in pp collisions at s = 13 TeV at midrapidity (|y| < 0.5) was measured with the ALICE detector at the LHC, covering an unprecedented transverse-momentum range of 1.6 < pT< 50 GeV/c. The meson is reconstructed via the ω → π+π−π0 decay channel. The results are compared with various theoretical calculations: PYTHIA8.2 with the Monash 2013 tune o
This article presents a search for a heavy charged Higgs boson produced in association with a top quark and a bottom quark, and decaying into a W boson and a 125 GeV Higgs boson h. The search is performed in final states with one charged lepton, missing transverse momentum, and jets using proton-proton collision data at s = 13 TeV recorded with the ATLAS detector during Run 2 of the LHC at CERN. T
A search for T and Y vector-like quarks produced in proton-proton collisions at a centre-of-mass energy of 13 TeV and decaying into Wb in the fully hadronic final state is presented. The search uses 139 fb−1 of data collected by the ATLAS detector at the LHC from 2015 to 2018. The final state is characterised by a hadronically decaying W boson with large Lorentz boost and a b-tagged jet, which are
Mental simulation theories of language comprehension propose that people automatically create mental representations of objects mentioned in sentences. Mental representation is often measured with the sentence-picture verification task, wherein participants first read a sentence that implies the object property (i.e., shape and orientation). Participants then respond to an image of an object by in

The Middle East, home to 6.3 percent of the world’s population and containing only 1.4 percent of the world’s renewable fresh water, is experiencing an increasing water scarcity crisis.1 The UN presented an alarming report during the last World Water Forum in March 2009 painting a bleak picture of increasing demand and diminishing water supplies.2 Scientifically, the Middle East ran out of water i
Kortvariga intensiva regn med varaktighet upp till en timme åren 1980–2007 från nederbördsmätare i Malmöhar analyserats för att finna intensiteter med lång återkomsttid. Oberoende observationer för olika stationer harsammanförts till en serie till vilken sannolikhetsfördelningar anpassats. Korttidsregnmätningars tillförlitlighetdiskuteras. De extrema händelserna har behandlats individuellt. För atShort-term intensive storms of duration up to an hour the years 1980–2007 from rain gauges in Malmö havebeen analyzed to find intensities of long return periods. Non-dependent observations from different stationshave been combined into a series to which probability functions have been adjusted. The extreme events havebeen investigated individually. The reliability of rain measurements is discussed
The needs and wishes of older people have often been forgotten in urban planning in recent decades. Yet already today, more than one billion of the world‘s population is over 60 years old, and according to the World Health Organisation (WHO), one in six people will be over 60 by 2030 - an increase to 1.4 billion by 2030 and up to 2.1 billion by 2050 (WHO, 2024). Like many European countries, Switz
