Final results of the search for ν μ → ν e oscillations with the OPERA detector in the CNGS beam
Journal of High Energy Physics, 2018 The OPERA experiment has discovered the tau neutrino appearance in the CNGS muon neutrino beam, in agreement with the 3 neutrino flavour oscillation hypothesis.

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.

New limits on neutrino non-unitary mixings based on prescribed singular values
Journal of High Energy Physics, 2020 Singular values are used to construct physically admissible 3-dimensional mixing matrices characterized as contractions. Depending on the number of singular values strictly less than one, the space of the 3-dimensional mixing matrices can be split into ...

Neutrino mixing: A4 variations
Physics Letters B, 2016 In the context of the non-Abelian discrete symmetry $A_4$, the neutrino mass matrix has been studied extensively. A brief update is presented to focus on the conceptual shift from tribimaximal mixing ($θ_{13} = 0$, $θ_{23} = π/4$, $\tan^2 θ_{12} = 1/2$) to $\underline{\rm cobimaximal}$ mixing ($θ_{13} \neq 0$, $θ_{23} = π/4$, $δ_{CP} = \pm π/2$) which ...

Two Micron‐Size Dark Dimensions
Fortschritte der Physik, Volume 73, Issue 8, August 2025.Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Resonant neutrino interaction and mixing [PDF]
Physics Letters B, 1995 We investigate the resonant interaction of neutrinos in matter in the presence of mixing. At energies near the W resonance, oscillations are absent; the survival probability of electron antineutrinos is suppressed due to the presence of open inelastic channels.

Geophysical Research Letters, Volume 52, Issue 14, 28 July 2025.Abstract Ice is mechanically and dielectrically anisotropic. The degree of anisotropy evolves dynamically as ice crystals align during deformation into macroscopic patterns termed ice fabric. Radar polarimetry is an emerging tool to detect such patterns, particularly using nadir‐looking antenna geometries sensitive to horizontal anisotropy.

Parametrizing the neutrino mixing matrix [PDF]
Physical Review D, 2003 We propose parametrizations of the neutrino mixing matrix. We discuss several Ansatzes: in some of them $V_{e3}=0$ but in others $V_{e3}$ typically ``comes out'' to be of order $\simeq 0.05.$

On the photon–classical electromagnetic field relationship
Annals of the New York Academy of Sciences, Volume 1549, Issue 1, Page 11-21, July 2025.Abstract This paper discusses how the two ways in which the wavefunction of a free‐propagating photon can be introduced—starting from the relativistic energy−momentum relationship or based on the electromagnetic field, in particular on Riemann–Silberstein vectors—are not entirely equivalent since they can lead to different consequences regarding photon
