Kurzdarstellung von openCost und seiner Bedeutung in Hinblick auf das Informationsbudget..

The existence of Higgs-like scalars, which could be produced atelectron-positron collider in association with a Z boson, is predictedby many BSM models and, assuming a smallcoupling to the Z boson, still not excluded by experimental data.Prospects for discovering such an scalar at future Higgsfactories have been studied by different methods.The most model-independent one is based on the recoil of the newparticle against the Z, since this is independent of the decay modes of the new scalar.Based on this method, searches were performed for any mass of thescalar and for two different decays of the Z boson, to a pair ofmuons and to a pair of electrons. The combination of the limits obtainedby the two Z decay modes was also performed.For detector-level simulations, the study takes the ILD detector conceptand ILC parameters at 250 GeV as example.

The European XFEL is in operation since 2017 with a maximum energy of 17.5 GeV in short-pulse (SP) mode, consisting of 0.65-ms long bunch trains at 10 Hz repetition rate. The accelerator can deliver up to 2700 electron bunches every 100 ms, with a spacing between bunches of 220 ns.After eight years of successful operation the accelerator team, with strong support from the XFEL strategy process, is working to define an accelerator upgrade scenario for possible implementation in the next decade.The main goal of the upgrade is to facilitate more bunches per second with larger bunch spacing while maintaining the high energy of the beam, a world record amongst FEL machines.

I will consider correlation functions of five scalar BPS operators in N=4 SYM theory from various perspectives, and present recent results on their computation..

Axion as a non-thermal dark matter could significantly change its cosmological evolution by interacting with a thermalized hidden sector. We study pure hidden Yang-Mills (YM) gauge fields as an example. [...]

Workshop: Unter dem Begriff Open-Access-Monitoring wird die Erfassung und Analyse von Informationen, Publikationen, Kosten und weiteren Parametern des Open-Access-Publizierens verstanden. Mit Blick auf Zielmarken sowie auf die ökonomische Dimension der Open-Access-Transformation gewinnt der Umgang mit diesen Informationen weiter an Relevanz.Dieser Workshop wird gemeinsam von den DFG-geförderten Projekten OA Datenpraxis, openCost und Transform2Open veranstaltet und richtet sich an Professionals, die sich mit Monitoring beschäftigen.Ziel des Workshops ist es, gemeinsam mit den Teilnehmenden aktuelle Fragestellungen des Open-Access-Monitorings zu diskutieren.
