Abstract The Karlsruhe Tritium Neutrino (KATRIN) experiment is designed to measure a high-precision integral spectrum of the endpoint region T 2 β decay, with primary goal probing absolute mass scale neutrino. After first tritium commissioning campaign in 2018, has been regularly running since 2019, and its two measurement campaigns already achieved sub-eV sensitivity. 1000 days data-taking, KATRIN’s design sensitivity 0.2 eV at 90% confidence level.

In this study, we performance of TRISTAN module, component eventual 9-module system....
Kaonic atoms measure the antikaon-nucleus interaction at almost zero relative energy, allowing one to determine basic low-energy quantum chromodynamics (QCD) quantities, namely, antikaon-nucleon ( K ¯ N) scattering lengths. The latter are important for extracting sigma terms which built on symmetry breaking part of Hamiltonian, thereby providing a chiral and SU(3) symmetries breaking. After discussing their relations kaonic atoms, we describe most precise measurement in literature hydrogen,...

Abstract Precision electron spectrometry in the keV range has always been considered a challenging task. The reconstruction of original energy from detected signal is not trivial because multiple effects modify kinetic along its path. If correctly accounted for, these can spoil and bias reconstructed with dramatic reduction accuracy precision. In this paper we address one most critical aspects spectrometry: generally unknown effect detector entrance window. We show that, MonteCarlo-based...
