Research Offers in our Group

We are involved in the ATLAS experiment at the LHC and are working on various analyses. On the hardware side, we are involved in the upgrade of the pixel detector. Theses usually cover the following topics:

• Development of algorithms for the reconstruction and identification of particle signatures in the ATLAS detector, in particular decays of hadronic tau-lepton decays. We use modern AI methods for pattern recognition.
• “Big data” analyses with the ATLAS data set: precise measurements of the properties of the Higgs boson and other parameters of the Standard Model, and searches for particles beyond the Standard Model. AI methods to suppress background processes and statistical methods to interpret the results.
• Construction of the new ATLAS ITk pixel detector: work in the assembly and quality control before they are sent to CERN.

We are working on several future experiments. Here, simulations have to be created, physics studies have to be performed based on simulations and the experiments themselves (especially the detectors) have to be developed and optimized. In all areas there are opportunities to do a thesis and we can offer work on the following future experiments:

• The Lohengrin experiment at the ELSA accelerator at PI looking for “dark” photons
• The BabyIAXO (and later the IAXO) experiment at DESY looking for solar axions
• Experiments at a future e+e- “Higgs factory” (FCCee, ILC, etc.) after the end of the LHC

We work on gaseous detectors in various fields:

• Precise detection of neutrons and low-energy X-rays
• Large track chambers for future experiments
• Development of readout electronics and monitoring systems for large detector systems, including programming of FPGAs
• Work on a particle detector experiment for schools
