Description
The KATRIN experiment aims to measure the neutrino mass by precision spectroscopy of tritium β-decay. Recently, KATRIN has improved the upper bound on the electron-neutrino mass to 0.8 eV/c² at 90% CL and is continuing to take data.
Beyond the neutrino mass, the ultra-precise measurement of the β-spectrum at KATRIN can reveal further distinct signatures of new physics. Current investigations involve searching for an eV-scale sterile neutrino motivated by several anomalies, specific Lorentz invariance violating parameters only accessible via interaction processes such as at KATRIN, and probing the local relic neutrino background by threshold-free neutrino capture on tritium. Additionally, searches are being conducted for general neutrino interactions, enabling a broad search for novel interactions, and for neutrino-DM interactions using the dark MSW effect.
This presentation will highlight a selection of new physics searches carried out at KATRIN and present their most recent results.
