Evidence of Electron Neutrino Appearance in a Muon Neutrino Beam [PDF]

open access: yes, 2013
The T2K collaboration: reports evidence for electron neutrino appearance at the atmospheric mass splitting, |\Delta m_{32}^2|=2.4x10^{-3} eV^2. An excess of electron neutrino interactions over background is observed from a muon neutrino beam with a peak ...

An Algebraic Roadmap of Particle Theories

open access: yesAnnalen der Physik, Volume 537, Issue 4, April 2025.
Algebraic models of particle physics are often met with recurring obstacles. An ideal algebraic model should ‘1e conform to the Coleman‐Mandula theorem, ‘2e evade familiar fermion doubling problems, ‘3e naturally explain the Standard Model's chirality, ‘4e exclude B‐L gauge symmetry at low energy, and ‘5e explain the existence of three generations ...

Neutrino mass, electron capture, and the shake-off contributions [PDF]

open access: yes, 2016
Electron capture can determine the electron neutrino mass, while the beta decay of Tritium measures the electron antineutrino mass and the neutrinoless double beta decay observes the Majorana neutrino mass. Electron capture e. g.

Energetic Compact Strokes as the Major Source of Downward Terrestrial Gamma‐Ray Flashes in Winter Thunderstorms

open access: yesGeophysical Research Letters, Volume 52, Issue 6, 28 March 2025.
Abstract Terrestrial gamma‐ray flashes (TGFs) are short bursts of intense gamma radiation associated with lightning discharges. Although thousands of TGFs have been observed from space, TGFs detected at ground level, known as downward TGFs, are still very limited, and their relationship with lightning discharge processes remains elusive. Here we report

Studies of Parity Violation in Atoms

open access: yesAnnalen der Physik, Volume 537, Issue 2, February 2025.
This article provides an overview of atomic parity violation (APV), emphasizing its role in testing the Standard Model and probing new physics. The review discusses manifestations of APV, including nuclear‐spin‐independent and dependent effects, and explores isotopic comparison as a method for precision measurements.

Atmospheric Neutrinos

open access: yesAdvances in High Energy Physics, 2012
Atmospheric neutrinos are produced as decay products in hadronic showers resulting from collisions of cosmic rays with nuclei in the atmosphere. Electron-neutrinos and muon-neutrinos are produced mainly by the decay chain of charged pions to muons to ...

Multi‐Photon 3D Laser Micro‐Printed Plastic Scintillators for Applications in Low‐Energy Particle Physics

open access: yesAdvanced Functional Materials, Volume 35, Issue 2, January 9, 2025.
Many modern detector systems require structured scintillators in combination with photo‐detectors. This requirement can be fulfilled by 3D printing plastic scintillators which becomes more and more relevant. However, the resolution and surface quality of 1‐photon‐based 3D printing techniques are not sufficient for many applications.
