Searches for lepton-flavour-violating decays of the Higgs boson in s=13\sqrt{s}=13 TeV pp\mathit{pp} collisions with the ATLAS detector

This Letter presents direct searches for lepton flavour violation in Higgs boson decays, H → eτ and H → μτ , performed with the ATLAS detector at the LHC. The searches are based on a data sample of proton–proton collisions at a centre-of-mass energy √s = 13 TeV, corresponding to an integrated luminosity of 36.1 fb−1. No significant excess is observed above the expected background from Standard Model processes. The observed (median expected) 95% confidence-level upper limits on the leptonflavour-violating branching ratios are 0.47% (0.34+0.13−0.10%) and 0.28% (0.37+0.14−0.10%) for H → eτ and H → μτ , respectively.publishedVersio

Search for flavour-changing neutral currents in processes with one top quark and a photon using 81 fb⁻¹ of pp collisions at \sqrts = 13 TeV with the ATLAS experiment

A search for flavour-changing neutral current (FCNC) events via the coupling of a top quark, a photon, and an up or charm quark is presented using 81 fb−1 of proton–proton collision data taken at a centre-of-mass energy of 13 TeV with the ATLAS detector at the LHC. Events with a photon, an electron or muon, a b-tagged jet, and missing transverse momentum are selected. A neural network based on kinematic variables differentiates between events from signal and background processes. The data are consistent with the background-only hypothesis, and limits are set on the strength of the tqγ coupling in an effective field theory. These are also interpreted as 95% CL upper limits on the cross section for FCNC tγ production via a left-handed (right-handed) tuγ coupling of 36 fb (78 fb) and on the branching ratio for t→γu of 2.8×10−5 (6.1×10−5). In addition, they are interpreted as 95% CL upper limits on the cross section for FCNC tγ production via a left-handed (right-handed) tcγ coupling of 40 fb (33 fb) and on the branching ratio for t→γc of 22×10−5 (18×10−5). © 2019 The Author(s

Measurement of the inclusive cross-section for the production of jets in association with a Z boson in proton–proton collisions at 8 TeV using the ATLAS detector

Abstract: The inclusive cross-section for jet production in association with a Z boson decaying into an electron–positron pair is measured as a function of the transverse momentum and the absolute rapidity of jets using 19.9 fb-1 of s=8 TeV proton–proton collision data collected with the ATLAS detector at the Large Hadron Collider. The measured Z+ jets cross-section is unfolded to the particle level. The cross-section is compared with state-of-the-art Standard Model calculations, including the next-to-leading-order and next-to-next-to-leading-order perturbative QCD calculations, corrected for non-perturbative and QED radiation effects. The results of the measurements cover final-state jets with transverse momenta up to 1 TeV, and show good agreement with fixed-order calculations

Silicon LEDs in FinFET technology

We present what to our best knowledge is the first forward operating silicon light-emitting diode (LED) in fin-FET technology. The results show near-infrared (NIR) emission around 1100 nm caused by band-to-band light emission in the silicon which is uniformly distributed across the lowly doped active light-emitting area. We also propose further improvements to exploit the full potential of this structure

Being "low on the totem pole":What makes work worthwhile for medical assistants in an era of primary care transformation

BACKGROUND: Primary care is undergoing a transformation to become increasingly team-based and multidisciplinary. The medical assistant (MA) is considered a core occupation in the primary care workforce, yet existing studies suggest problematic rates and costs of MA turnover. PURPOSE: We investigated what MAs perceive their occupation to be like and what they value in it to understand how to promote sustainable employability, a concept that is concerned with an employee's ability to function and remain in their job in the long term. APPROACH: We used a case of a large, integrated health system in the United States that practices team-based care and has an MA career development program. We conducted semistructured interviews with 16 MAs in this system and performed an inductive analysis of themes. RESULTS: Our analysis revealed four themes on what MAs value at work: (a) using clinical competence, (b) being a multiskilled resource for clinic operations, (c) building meaningful relationships with patients and coworkers, and (d) being recognized for occupational contributions. MAs perceived scope-of-practice regulations as limiting their use of clinical competence. They also perceived task similarity with nurses in the primary care setting and expressed a relative lack of performance recognition. CONCLUSION: Some of the practice changes that enable primary care transformation may hinder MAs' ability to attain their work values. Extant views on sustainable employability assume a high bar for intrinsic values but are limited when applied to low-wage health care workers in team-based environments. PRACTICE IMPLICATIONS: Efforts to effectively employ and retain MAs should consider proactive communications on scope-of-practice regulations, work redesign to emphasize clinical competence, and the establishment of greater recognition and respect among MAs and nurses
