Working group of Prof. Dr. Ariane Frey

Our working group is deeply involved with the Belle II experiment in Japan, a cutting-edge research project in particle physics. Our focus is on analyzing the B-physics being studied in this experiment. We conduct detailed studies to understand the properties and behaviours of B-mesons, providing crucial insights into the fundamental forces and particles of the universe. Additionally, we work on accelerator studies to optimize the performance and efficiency of the experiment. A significant part of our efforts is the Vertex Detector Upgrade, where we test CMOS sensors to develop innovative technologies and methods that improve measurement precision and enhance the quality of experimental data.

  • Student Project: Simulation of Irradiated TJ-Monopix2 Sensors - This project, part of a Bachelor's/Master's thesis or internship, involves simulating irradiated TJ-Monopix2 sensors and comparing results with test beam data. The goal is to model the sensor's response to radiation and validate it against experimental data, aiding in the optimization of radiation-hard pixel sensors.
