In recent years, the focus shifted to light DM particles; this was different in the early 90s: "negative results in annihilation searches, in accelerator experiments, and in direct-detection experiments had tended to shift the focus of interest to progressively heavier WIMPs." A. Gould, APJ 1992

It was nice to visit the underground lab with LZ and XENON colleagues ;) Hall C - shown here - is one of the sites for the future XLZD experiment.

With XENONnT data we looked for spontaneous radiation as predicted by dynamical quantum collapse models. No signal above background was observed, and we set constraints on the free parameters of two benchmark models. With leading contributions by my PhD student Alex Bismark: arxiv.org/abs/2506.05507

The Bedretto tunnel connects Ticino with the Furka tunnel, and is merely a two hours train ride away from Zurich. And, we were quite happy and surprised to discover a yogurteria di montagna directly in the train station in Airolo

Last week my colleagues and I visited the Bedretto underground lab, operated by the @ethz.ch (bedrettolab.ethz.ch/en/home/). For now, umbrellas
to protect our small neutron detectors were needed, but in the future we might outfit the deep tunnel (~1500 m overburden) for rare event searches ;)

Naturally, our XLZD submission is the last in the alphabetical list of inputs to the 2026 European Strategy for Particle Physics. If you're curious about its physics, design, technical challenges, timeline, and funding (all in just 8 pages ;-) have a look at the PDF: indico.cern.ch/event/143985...

If you like liquid xenon detectors - our article on commissioning Xenoscope, a 2.6 m tall dual-phase TPC demonstrator for XLZD, is now online. Just in time for the next run starting up after Easter ;-) iopscience.iop.org/article/10.1...

Neutrinos may or may not be shrinking, but this is a great new result from the KATRIN experiment: new direct upper limit on the (effective electron) neutrino mass of 0.45 eV (90% CL). This comes from precision measurements of tritium β-decays in a huge spectrometer: www.science.org/doi/10.1126/...
