Sterile-neutrino search based on 259 days of KATRIN data

Himal Acharya, Max Aker, Dominic Batzler +132

Neutrinos are the most abundant fundamental matter particles in the Universe and play a crucial role in particle physics and cosmology. Neutrino oscillation, discovered about 25 ye…

Demonstration of tritium adsorption on graphene

Genrich Zeller, Desedea Diaz Barrero, Paul Wiesen +9

In this work, we report on studies of graphene exposed to tritium gas in a controlled environment. The single layer graphene on a /Si substrate was exposed to 400 m…
