Konferensbidrag (refereegranskat)abstract
- The experimental observation of charged Higgs bosons, H±, which are predicted by several models with an extended Higgs sector, would indicate physics beyond the Standard Model. This note presents the results of a search for charged Higgs bosons in 14.7 fb−1 of pp collision data at √ s = 13 TeV recorded by the ATLAS detector at the LHC. The search targets the τ+jets channel in top-quark-associated H ± production with a hadronically decaying W boson and τ lepton in the final state. No evidence of a charged Higgs boson is found. For the mass range of mH± = 200 − 2000 GeV, upper limits are set on the production cross section of the charged Higgs boson with the subsequent decay H± → τν in a range of 2.0 − 0.008 pb.

- Medical professionals are increasingly assuming the role of maker and creator. At the same time, digital innovations, as part of evolving information infrastructures, are becoming increasingly prevalent in healthcare. In this paper, we adopt a Schönian approach to understand how a medical professional, who is not an IS designer by trade, engages in the design of digital practice - turning what may appear as a failed digital innovation effort into a successful design of digital practice. Our inquiry suggests three pragmatic principles that call for further investigation: (a) professionals can make a significant contribution to design work by inventing means for fact-based, reflective engagement with the situation; (b) the reorganization of work practice involves organizational design, information system design, and communication design; and (c) developing design as digital practice entails the development of fact-based design practice and must engage practical theories.

- Acting out Disease: How Patient Organizations Shaped Modern Medicine (ActDisease) explores the history of patient organizations in 20th century Europe. By combining traditional historiographic methods with text mining techniques, the project aims to shed light on how patient organizations co-constructed concepts of and management of disease. Part of the project is to digitize print sources and build a digital corpus for historical text mining. The corpus consists of periodical publications from selected British, French, German and Swedish patient organizations, a type of material that poses a number of challenges in scan quality, layout, and lack of consistency. This paper discusses the technical process of building the ActDisease corpus from digitizing patient organization periodicals to OCR post-processing. It touches upon the methodological questions and challenges of curating a corpus of fragmented and heterogeneous historical source material tailored to a specific project.

- Damage mechanics is often modeled by using adhoc or phenomenological methodologies, which is useful but challenging to generalize. Especially inapplications with several length scales, a homogenization procedure leads to ametamaterial to be modeled by the generalized mechanics. We aim for a unifiedtheory of generalized damage mechanics by following a variation purelyalformulation.

- The IceCube Neutrino Observatory first observed a diffuse flux of high energy astrophysical neutrinos in 2013. Since then, this observation has been confirmed in multiple detection channels such as high energy starting events, cascades, and through-going muon tracks. Combining these event selections into a high statistics global fit of 10 years of IceCube's neutrino data could strongly improve the understanding of the diffuse astrophysical neutrino flux: challenging or confirming the simple unbroken power-law flux model as well as the astrophysical neutrino flux composition. One key component of such a combined analysis is the consistent modelling of systematic uncertainties of different event selections. This can be achieved using the novel SnowStorm Monte Carlo method which allows constraints to be placed on multiple systematic parameters from a single simulation set. We will report on the status of a new combined analysis of through-going muon tracks and cascades. It is based on a consistent all flavor neutrino signal and background simulation using, for the first time, the SnowStorm method to analyze IceCube's high-energy neutrino data. Estimated sensitivities for the energy spectrum of the diffuse astrophysical neutrino flux will be shown.

A model-independent analysis of neutrino flares detected in IceCube from X-ray selected blazars

- Blazars are among the most powerful steady sources in the Universe. Multi-messenger searches for blazars have traditionally focused on their gamma-ray emission, which can be produced simultaneously with neutrinos in photohadronic interactions. However, X-ray data can be equally vital to constrain the SED of these sources, since the hadronically co-produced gamma-rays could get absorbed by the ambient photon fields and cascade down to X-ray energies before escaping. In this work, we present the outline for an untriggered, time-dependent analysis of neutrino flares from the direction of X-ray selected blazars using 10 years of IceCube data. A binomial test will be performed on the population to reveal if a subcategory of sources has statistically significant emission. The sources are selected from RomaBZCat, and the p-values and best-fit flare parameters are obtained for each source using the method of unbinned likelihood maximisation.

A New Search for Neutrino Point Sources with IceCube

Konferensbidrag (refereegranskat)abstract
- The IceCube Neutrino Observatory, deployed inside the deep glacial ice at the South Pole, is the largest neutrino telescope in the world. While eight years have passed since IceCube discovered a diffuse flux of high-energy astrophysical neutrinos, the sources of the vast majority of these neutrinos remain unknown. Here, we present a new search for neutrino point sources that improves the accuracy of the statistical analysis, especially in the low energy regime. We replaced the usual Gaussian approximations of IceCube's point spread function with precise numerical representations, obtained from simulations, and combined them with new machine learning-based estimates of event energies and angular errors. Depending on the source properties, the new analysis provides improved source localization, flux characterization and thereby discovery potential (by up to 30%) over previous works. The analysis will be applied to IceCube data that has been recorded with the full 86-string detector configuration from 2011 to 2020 and includes improved detector calibration.
