Neutrino Mass Measurements

This lecture covers the measurement of neutrino masses through the study of electron energy spectra in beta decays, focusing on the KATRIN experiment and the principle of determining neutrino mass. It also discusses direct measurements of electron, muon, and tau neutrino masses, as well as the experimental setup of the spectrometer used in these measurements. The lecture delves into the results of the KATRIN experiment, the Heidelberg-Moscow experiment, and the NEMO3 experiment, providing insights into the current status and future prospects of neutrino mass measurements.
