The fact that neutrinos carry a non-vanishing rest mass is evidence of physics beyond the Standard Model elementary particles. Their absolute bears important relevance from particle to cosmology. In this work, we report on search for effective electron antineutrino with KATRIN experiment. performs precision spectroscopy tritium $\beta$-decay close kinematic endpoint. Based first five neutrino-mass measurement campaigns, derive best-fit value $m_\nu^{2} =...
Abstract The projected sensitivity of the effective electron neutrino-mass measurement with KATRIN experiment is below 0.3 eV (90 % CL) after 5 years data acquisition. affected by increased rate background electrons from KATRIN’s main spectrometer. A special shifted-analysing-plane (SAP) configuration was developed to reduce this a factor two. complex layout electromagnetic fields in SAP requires robust method estimating these fields. We present paper dedicated calibration using conversion...
