The Karlsruhe Tritium Neutrino experiment KATRIN is investigating the endpoint region of tritium beta decay. KATRIN uses a strong windowless gaseous molecular tritium source combined with a huge MAC-E-Filter as high resolution electron spectrometer. In order to achieve the goal of a neutrino mass sensitivity of less than 0.3 eV, KATRIN has successfully pushed many technologies to their limits...
A Strangeness Odyssey: Kaonic Atom Measurements at the DAΦNE Collider. In particle physics, understanding the low-energy strong interaction remains a significant challenge, demanding new experimental data as input and validation. Among the promising approaches, X-ray spectroscopy of kaonic atoms offers a unique window into the antikaon-nucleon interaction at threshold. The DEAR and SIDDHARTA...
We give an overview on recent results for masses, binding energies and the internal structure of exotic light and heavy-light four-quark states determined in a functional approach to QCD.
