TL;DR: In this article, the authors present expressions for the coefficient of the transverse electron polarization R, including the corrections due to second forbidden and radiative terms, and demonstrate that a measurement of both R and the electron asymmetry coefficient A allows a model-independent test of T-violation.

TL;DR: In this article, two data sets representing the two principal experimental techniques used to study the β-decay of short-lived fission fragments are analyzed, and the average endpoint and electron energies for nuclei with similar Q-values are the same within statistical accuracy in the two sets.

TL;DR: In this paper, the 2p-1s atomic transition in pionic hydrogen has been studied with the help of a point-focusing graphite diffraction spectrometer, and a strong interaction shift of -3.9±1.7 eV was derived.
Abstract: The 2p-1s atomic transition in pionic hydrogen has been studied with the help of a point-focusing graphite diffraction spectrometer. The transition energy was measured to be E(2p-1s)=2433.5±1.7 eV. From this result a strong interaction shift of -3.9±1.7 eV was derived. The Kα x-ray yield in the 2.7 atm hydrogen target at 40 K was found to be 0.025±0.013 per stopped pion.

TL;DR: In this article, the authors discuss the various aspects of the neutrino mass problem and discuss the interplay of different subfields of physics, including astrophysics, particle physics, nuclear physics, and even geophysics.
Abstract: In these lectures we shall discuss the various aspects of the neutrino mass problem This has been an interesting story for several reasons First, if neutrinos are massive one has to modify the “standard” (Weinberg-Salam-Glashow) theory of weak interactions A nonvanishing neutrino mass would represent a strong argument for grand unification with its tremendous mass scale Second, the search for neutrino mass involves an interplay of very different, and often isolated, subfields of physics Thus we shall mention astrophysics, particle physics, nuclear physics, and even geophysics It is quite unusual that results of so many disciplines contribute to a common goal
