Measurement and interpretation of same-sign W boson pair production in association with two jets in pp collisions at s = 13 TeV with the ATLAS detector

This paper presents the measurement of fducial and diferential cross sections for both the inclusive and electroweak production of a same-sign W-boson pair in association with two jets (W±W±jj) using 139 fb−1 of proton-proton collision data recorded at a centre-of-mass energy of √s = 13 TeV by the ATLAS detector at the Large Hadron Collider. The analysis is performed by selecting two same-charge leptons, electron or muon, and at least two jets with large invariant mass and a large rapidity diference. The measured fducial cross sections for electroweak and inclusive W±W±jj production are 2.92 ± 0.22 (stat.) ± 0.19 (syst.)fb and 3.38±0.22 (stat.)±0.19 (syst.)fb, respectively, in agreement with Standard Model predictions. The measurements are used to constrain anomalous quartic gauge couplings by extracting 95% confdence level intervals on dimension-8 operators. A search for doubly charged Higgs bosons H±± that are produced in vector-boson fusion processes and decay into a same-sign W boson pair is performed. The largest deviation from the Standard Model occurs for an H±± mass near 450 GeV, with a global signifcance of 2.5 standard deviations

Going home? An ethnographic study of assessment of capacity and best interests in people with dementia being discharged from hospital

Objective: To understand how, on medical wards, judgements about capacity and best interests with respect to going home are made – in line with the Mental Capacity Act 2005 – for people with dementia and how decision-making around hospital discharge for people with dementia and their families might be improved. Design: Ward-based ethnography. Observational data were captured through: detailed fieldnotes, in-depth interviews, medical-record review and focus groups. Themes and key issues identified using constant comparative analysis of 29 cases. Participants: Theoretical sampling of key stakeholders, including patients with dementia (with and without residence capacity), their relatives and a range of practitioners from the multi-disciplinary teams providing health and social care. Setting: Three hospital wards (acute and rehabilitation) in two hospitals within two NHS healthcare trusts in the North of England over a period of nine months between 2008 and 2009. Results: Analysis highlights the complexity of judgements about capacity and best interests, along with the workings of the MCA, in relation to decisions about place of residence for people with dementia facing discharge from hospital. Five key themes emerged from data: the complexity of borderline decisions; the requirement for better understanding of assessment approaches in relation to residence capacity; the need for better documentation; the importance of narrative; and the crucial relevance of time and timing in making these decisions. Conclusions: We need: more support and training for practitioners, as well as support for patients and families; clarity about the information to be imparted to the person with dementia; more advocacy for people with dementia; appropriate assessments embedded in routine clinical practice; the patient with dementia to be centre-stage in this decision-making; and properly resourced step-down or rehabilitation units to facilitate timely and good decision-making about place of residence
