Can miniscule Dark Matter charges explain why neutrinos are so light?

The Institute of Physics celebrates the 20 high-impact publications from Germany in 2025 with a special issue. As was already the case in 2024, the list once again includes a publication from the University of Münster in the Journal of Cosmology and Astroparticle Physics. "We investigated whether Dark Matter might not be completely electrically neutral after all. That would not only explain its stability, but also why neutrinos are so much lighter than other elementary particles," says Prof. Michael Klasen of the Institute for Theoretical Physics. "The fact that this idea from our postdoc, Vishnu P.K., has now been recognized by the Institute of Physics shows that it is gaining attention worldwide." Also involved in the work were University of Münster doctoral student L. Wiggering and Dr. Sudip Jana of the Max Planck Institute for Nuclear Physics in Heidelberg.
