Astroparticle Physics with Neutrinos and Dark Matter

by Dr Dimitrios Papoulias (University of Hamburg)

Monday 9 Feb 2026, 11:00 → 12:00 Europe/Athens

Ιn this seminar, I will present a concise overview of my recent work on astroparticle physics phenomenology, focusing on neutrinos and dark matter. I will mainly discuss analyses of coherent elastic neutrino–nucleus scattering (CEvNS) data from stopped-pion sources (COHERENT), reactor neutrino experiments (Dresden-II and CONUS+) as well as studies of solar neutrinos in direct dark matter detection experiments such as XENONnT and PandaX-4T. I will explore new-physics scenarios involving nonstandard interactions, sterile neutrinos, and new particle production via neutrino upscattering, demonstrating strong and robust complementarity with the DUNE Near Detector. I will then turn to dark matter phenomenology, discussing the impact of new physics on the neutrino fog and presenting recent constraints on boosted dark matter from XENONnT and LUX-ZEPLIN. Finally, I will show how reactor neutrino experiments can probe axion-like particles, and how spallation source experiments provide a powerful avenue to search for artificially produced sub-GeV dark matter, significantly extending the physics reach of neutrino facilities.
