Talks (non-conference)

Cosmological evolution of axion field could be significantly modified in the presence of a thermalized hidden sector. We study pure hidden Yang-Mills (YM) gauge fields as an example, which generates friction through the sphaleron processes. [...]

FLASHlab@PITZ is a new setup for radiobiological irradiation experiments at the PITZ (Photo Injector Test stand at DESY, Zeuthen) accelerator. The main purpose is to investigate the FLASH effect and optimize irradiation parameters. [...]

Motivation, options and practice

Understanding the shape of the Higgs potential and the nature of electroweak symmetry breaking is a central goal of particle physics. Extensions of the Standard Model (SM) Higgs sector can lead to rich phenomenology, including modified Higgs self-couplings, new scalar states, and strong first-order phase transitions in the early Universe—potentially sourcing a stochastic gravitational wave background.

The aim of the project openCost is to create a technical infrastructure that makes publication costs freely accessible and exchangeable via standardized interfaces and formats. This is supposed to enable cost transparency on an institutional, national, and international level.To achieve this, we are developing a standardized metadata schema to record, retrieve and map all publication costs of a scientific institution in a structured form.
