Description
The KArlsruhe TRItium Neutrino (KATRIN) experiment aims to measure the absolute mass of electron antineutrino with a sensitivity of better than $0.3~\mathrm{eV}$ at a $90\%$ confidence level (CL) by analyzing the endpoint region of the tritium $\beta$-decay spectrum. The experimental apparatus combines a high-luminosity gaseous molecular tritium source with a high-resolution electrostatic spectrometer. Recently, KATRIN has set a new upper limit on the neutrino mass of $0.45~\mathrm{eV}/c^2$ at a $90\%$ CL, using the first $25 \%$ of the total expected dataset[[1]]. This talk will present the underlying experimental principles, discuss the most recent results, and provide insights into KATRIN’s future neutrino mass measurements and selected new physics searches with KATRIN data.
