TL;DR: 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.

TL;DR: In this paper, a combined analysis of solar neutrino data from all phases of the Sudbury Neutrino Observatory was presented, which showed that particle identification information obtained from the proportional counters installed during the third phase improved background rejection in that phase of the experiment.

TL;DR: Project 8 as discussed by the authors uses cyclotron radiation emission spectroscopy (CRES) to estimate the absolute neutrino mass with a lower bound of 9(0.1 ) using an atomic tritium source.

TL;DR: This work demonstrates a fundamentally new approach to precision beta spectroscopy for future neutrino mass experiments by demonstrating single-electron detection in a novel radio-frequency spectrometer and the relativistic shift in the cyclotron frequency permits a precise electron energy measurement.

TL;DR: The focal plane detector system for the KArlsruhe TRItium Neutrino (KATRIN) experiment as discussed by the authors consists of a multi-pixel silicon p-i-n-diode array, custom readout electronics, two superconducting solenoid magnets, an ultra high-vacuum system, a high voxel system, calibration and monitoring devices, a scintillating veto, and a custom data-acquisition system.
