Experimental Particle and Astro-Particle Physics Seminar

Abstract: The XENONnT dark matter experiment operates a xenon time projection chamber designed to search for signals from weakly interacting massive particles (WIMPs). A fundamental aspect of this search is maintaining a detector with an exceptionally low background rate and low energy threshold. These characteristics not only increase our sensitivity to dark matter, but also allow the measurement of other rare processes.

In this talk, I will present XENONnT's latest WIMP search results alongside a recent milestone: the first indication of solar neutrinos via coherent elastic neutrino–nucleus scattering (CEvNS). Previously, solar neutrino measurements required dedicated kiloton-scale detectors; now XENONnT has achieved this with a tonne-scale detector. This result demonstrates that currently running dark matter experiments are becoming neutrino observatories in their own right.
