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
A set of measurements for the production of a W-boson in association with high-transverse-momentum jets is presented using 140 fb-1 of proton–proton collision data at a centre-of-mass energy of s=13 TeV collected by the ATLAS detector at the LHC. The measurements are performed in final states in which the W-boson decays into an electron or muon plus a neutrino and is produced in association with j
BACKGROUND: n-3 (ω-3) long-chain polyunsaturated fatty acids (n-3 LCPUFAs) have anti-inflammatory effects that may influence immune-mediated diseases.OBJECTIVES: We investigated whether higher maternal pregnancy intake of n-3 LCPUFA is associated with a lower incidence of infection in young children.METHODS: We used data from 3 Nordic cohorts: the Norwegian Mother, Father and Child Cohort study (M
Regardless of workplace, social workers today use standardized tools for investigation, assessment and treatment that, to varying degrees, prescribe what information should be collected, with what questions, and what should be done in what order. With an ethnomethodological gaze on situated action and context, this article explores how social workers ascribe meaning to a standardized tool for fami
High precision single-differential W±-boson production cross-sections as a function of electron or muon transverse momentum pT or their pseudorapity η, as well as double-differential cross-sections as functions of these variables, are measured in proton–proton collisions at centre-of-mass energies s=5.02 TeV and 13 TeV. The W-boson charge asymmetry as a function of lepton η is also measured. The d
INTRODUCTION: Total alloplastic replacement of the temporomandibular joint (TMJ) is a viable treatment option for severe TMJ disorders (TMDs) unresponsive to conservative approaches, as well as for reconstruction of congenital or acquired TMJ defects. However, clinical data on indications, outcomes, complications and long-term effects remain limited, and no global registry currently exists. This s
A search is presented for a heavy scalar (H) or pseudo-scalar (A) predicted by the two-Higgs-doublet models, where the H/A is produced in association with a top-quark pair (tt¯H/A), and with the H/A decaying into a tt¯ pair. The full LHC Run 2 proton–proton collision data collected by the ATLAS experiment is used, corresponding to an integrated luminosity of 139fb-1. Events are selected requiring
This paper describes an algorithm for reconstructing and identifying a highly collimated hadronically decaying τ-lepton pair with low transverse momentum. When two τ-leptons are highly collimated, their visible decay products might overlap, degrading the reconstruction performance for each of the τ-leptons. A dedicated treatment attempting to tag the τ-lepton pair as a single object is required. T
Three phases of archaeological investigations have been conducted in the area of the City Museum of Novi Sad at the Petrovaradin Fortress. In this study, we summarize the results of geoarchaeological research carried out during the third phase of excavations inside the museum building. The investigated area covered 27 m2. The approximately 0.60 m thick loessic sequence offers a unique opportunity
Statins may have anti-cancer effects against breast cancer, but evidence regarding their influence on the risk of contralateral breast cancer (CBC) remains inconclusive. In this updated study, incorporating a larger sample, extended follow-up, and landmark analyses, we reevaluated the association between post-diagnosis statin use and CBC incidence among women with breast cancer. Utilising the Dani
A search for pair production of vector-like leptons coupling to first- and second-generation Standard Model leptons is presented. The search is based on a dataset of proton-proton collisions at s = 13 TeV recorded with the ATLAS detector during Run 2 of the Large Hadron Collider, corresponding to an integrated luminosity of 140 fb−1. Events are categorised depending on the flavour and multiplicity
