His research centers on high-precision tests of fundamental symmetries in nature, particularly through the search for electric dipole moments (EDMs) of charged particles such as protons and deuterons. EDMs are critical probes for CP and T violation, offering insights into baryogenesis and physics beyond the Standard Model. The JEDI (Jülich Electric Dipole moment Investigations) collaboration, in which he is a key figure, aims to develop and conduct experiments using storage rings like COSY to detect these tiny asymmetries.
The scientific work involves advanced accelerator techniques, spin manipulation using radio-frequency electric fields, and polarimetry in magnetic storage rings. Although no individual publications or articles are listed in the provided text, the research direction clearly lies at the intersection of experimental particle physics, accelerator science, and precision measurement. The broader context includes participation in large-scale collaborative efforts such as the ERC Advanced Grant 'srEDM', highlighting institutional involvement in major European-funded research.
While no specific scientific awards or prizes are mentioned for Prof. Lehrach in the text, his leadership role in a high-profile international collaboration underscores significant recognition in the field. He likely supervises PhD and Master’s students as part of his academic duties, although no names are provided. His work also involves close collaboration with major institutions including the University of Ferrara and Brookhaven National Laboratory.
Prof. Lehrach is associated with the JEDI collaboration, which operates the JEDI detector at the Cooler Synchrotron (COSY) at Forschungszentrum Jülich. This team conducts beam time experiments, such as the measurement and optimization of spin coherence time for protons, and organizes regular collaboration meetings to advance the technical and scientific goals of the EDM search program.
