Limits on the Low-energy Electron Antineutrino Flux from the Brightest Gamma-Ray Burst of All Time

The Astrophysical Journal
The electron antineutrino flux limits are presented for the brightest gamma-ray burst (GRB) of all time, GRB221009A, over a range of 1.8–200 MeV using the Kamioka Liquid Scintillator Antineutrino Detector. Using multiple time windows ranging from minutes

Highlights from GERDA: Probing the Majorana Neutrino Mass at 100 meV

Universe, 2019
Since 2010, the Gerda experiment at Laboratori Nazionali del Gran Sasso (LNGS) operates searching for neutrinoless double beta decay ( 0 ν β β ) of 76 Ge to the ground and excited states of 76 Se.

Status and Perspectives of 2ϵ, ϵβ⁺ and 2β⁺ Decays

Particles, 2021
This paper reviews the main experimental techniques and the most significant results in the searches for the 2ϵ, ϵβ+ and 2β+ decay modes. Efforts related to the study of these decay modes are important, since they can potentially offer complementary ...

Magnetic Precursor to the Structural Phase Transition in V2O3

Advanced Electronic Materials, Volume 11, Issue 12, August 6, 2025.
V₂O₃, a model Mott insulator, undergoes a metal‐insulator transition linked to structural and magnetic transitions, though the underlying mechanism remains unclear. Through muon‐spin rotation and X‐ray diffraction on strain‐engineered thin films, a magnetic precursor to the structural transition is identified, emphasizing the key role of magnetism in ...

On neutrino-mediated potentials in a neutrino background

Journal of High Energy Physics, 2023
Abstract The exchange of a pair of neutrinos with Standard Model weak interactions generates a long-range force between fermions. The associated potential is extremely feeble, ∝ $$ {G}_F^2/{r}^5 $$ G F 2 /

Neutrino mass matrix with U(2) flavor symmetry and neutrino oscillations

, 1997
The three neutrino mass matrices in the $SU(5)\times U(2)$ model are studied focusing on the neutrino oscillation experiments. The atmospheric neutrino anomaly could be explained by the large $\nu_{\mu} - \nu_{\tau}$ oscillation.

Non-Zero Electric Charge of the Neutrino and the Solar Neutrino Problem [PDF]

, 1994
It has recently been shown that the neutrino can have non-zero electric charge in a number of gauge theories, including the Minimal Standard Model. Assuming non-zero neutrino charge, we develop a new approach to the solar neutrino problem.

Reactor neutrinos [PDF]

Comptes Rendus. Physique, 2005
We review the status and the results of reactor neutrino experiments, that toe the cutting edge of neutrino research. Short baseline experiments have provided the measurement of the reactor neutrino spectrum, and are still searching for important phenomena such as the neutrino magnetic moment.

Constraints on decay plus oscillation solutions of the solar neutrino problem [PDF]

, 2002
We examine the constraints on non-radiative decay of neutrinos from the observations of solar neutrino experiments. The standard oscillation hypothesis among three neutrinos solves the solar and atmospheric neutrino problems.

Human flaws and logical tools in engineering

The Canadian Journal of Chemical Engineering, Volume 103, Issue 8, Page 3512-3520, August 2025.
Abstract This paper explores the limitations of human cognition, especially in engineering research, emphasizing the need for mathematical models and methods to guide decision‐making and theory validation. While human cognition excels in certain tasks, it is prone to biases that can distort our understanding.
