Precision measurement of the electron energy-loss function in tritium and deuterium gas for the KATRIN experiment

The KATRIN experiment is designed for a direct and model-independent determination of the effective electron anti-neutrino mass via a high-precision measurement of the tritium

An upper limit on electron antineutrino mass from Troitsk experiment

An electron antineutrino mass has been measured in tritium $\ensuremath{\beta}$ decay in the Troitsk $\ensuremath{\nu}$-mass experiment. The setup consists of a windowless gaseous tritium source and

Final results from phase II of the Mainz neutrino mass searchin tritium ${\beta}$ decay

Abstract.This paper reports on the improved Mainz experiment on tritium $\beta$ spectroscopy which yields a 10 times higher signal to background ratio than before. The main experimental effects and

Improved Upper Limit on the Neutrino Mass from a Direct Kinematic Method by KATRIN.

An upper limit of 1.1 eV (90% confidence level) is derived on the absolute mass scale of neutrinos on the Karlsruhe Tritium Neutrino experiment KATRIN, which improves upon previous mass limits from kinematic measurements by almost a factor of 2 and provides model-independent input to cosmological studies of structure formation.

On the limited memory BFGS method for large scale optimization

The numerical tests indicate that the L-BFGS method is faster than the method of Buckley and LeNir, and is better able to use additional storage to accelerate convergence, and the convergence properties are studied to prove global convergence on uniformly convex problems.

First direct neutrino-mass measurement with sub-eV sensitivity

We report the results of the second measurement campaign of the Karlsruhe Tritium Neutrino (KATRIN) experiment. KATRIN probes the effective electron anti-neutrino mass, mν, via a high-precision
