Project 8 has demonstrated Cyclotron Radiation Emission Spectroscopy (CRES) as a novel technique for performing electron spectroscopy. Applying this method to highest energy electrons from tritium beta decay will lead to a direct neutrino mass measurement. A proof of this concept was performed with a waveguide detector utilizing monoenergetic 83mKr conversion electrons. The demonstrator has...

The assessment of the neutrino absolute mass scale remains one of the most crucial challenges in today particle physics and cosmology. Nuclear beta decay spectrum end-point study is currently the only experimental method to provide a model independent measurement of the lowest neutrino mass. HOLMES is an experiment to directly measure the electron neutrino mass by performing a calorimetric...

The goal of the \textbf{KA}rlsruhe \textbf{TRI}tium \textbf{N}eutrino (KATRIN) experiment is the determination of the electron neutrino mass $m(\nu_\mathrm{e})$ with a sensitivity of $0.2$\,eV/c$^2$ (90$\%$ C.L.)
by measuring an integrated energy spectrum of electrons from tritium $\beta$-decay.
The measurement of the tritium $\beta$-spectrum close to its endpoint at $E_0 =...

Highly-forbidden non-unique beta-decays are known to have electron-spectrum shapes which depend on the effective value of the axial vector coupling constant $g_{\rm A}$ [1, 2]. Resent calculations show that this is also the case for many first-forbidden non-unique decays. Moreover, the spectral shapes of first-forbidden $J^{+}\leftrightarrow \, J^{-}$ decays with $J\neq 0$ are found to depend...
