Particle physics and cosmology

Geraldine Servant is Lead Scientist in the DESY Theory group and Professor at the University of Hamburg. Her main area of research is the interplay between particle physics and cosmology, in particular regarding dark matter and the origin of the matter–antimatter asymmetry in the universe. She has been working on models of new physics at the terascale and their phenomenology at particle colliders, with special emphasis on the cosmological consequences, such as the nature of the electroweak phase transition in the early universe and dark-matter model building.

New findings and a flood of new data are expected in this field in the near future. These data come not only from the LHC accelerator at CERN in Geneva, but also from direct searches for dark matter in underground laboratories, from indirect searches using cosmic-ray telescopes, from low-energy frontier experiments searching for axion-like particles, from cosmological surveys and simulations of large-scale structures as well as from gravitational-wave astronomy.
