Flavour-symmetric type-II Dirac neutrino seesaw mechanism

Physics Letters B, 2018
We propose a Standard Model extension with underlying A4 flavour symmetry where small Dirac neutrino masses arise from a Type-II seesaw mechanism. The model predicts the “golden” flavour-dependent bottom-tau mass relation, requires an inverted neutrino ...

Radar Polarimetry in Glaciology: Theory, Measurement Techniques, and Scientific Applications for Investigating the Anisotropy of Ice Masses

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...

Cosmic Ray Counting Variability From Water‐Cherenkov Detectors as a Proxy of Stratospheric Conditions in Antarctica

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract This work examines atmospheric effects on cosmic ray counts observed by a Water‐Cherenkov detector at the Argentine Antarctic Marambio Station. We analyze the influence of ground‐level barometric pressure and geopotential height at various pressure levels on daily particle rates, finding the strongest association at 100 hPa, linked to ...

Supernova neutrino oscillations [PDF]

Nuclear Physics B - Proceedings Supplements, 2001
We discuss some possible influence of neutrino oscillations on physics of supernova mainly focusing on the observations of $\barν_e$, and present some analysis of SN1987A data in the light of three neutrino mixing scheme.

Dark dimension right-handed neutrinos confronted with long-baseline oscillation experiments

Journal of High Energy Physics
Right-handed neutrinos are naturally induced by dark extra dimension models and play an essential role in neutrino oscillations. The model parameters can be examined by the long-baseline neutrino oscillation experiments.

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 ...

Neutrino oscillations and scattering theory

Journal of High Energy Physics
We derive the neutrino oscillation probability in vacuum using scattering theory methods developed earlier in the context of collider physics [1–3]. It is computed from Feynman diagrams that combine neutrino production and detection processes into a ...

Phenomenology of neutrino oscillations [PDF]

Pramana, 2000
The phenomenology of solar, atmospheric, supernova and laboratory neutrino oscillations is described. Analytical formulae for matter effects are reviewed. The results from oscillations are confronted with neutrinoless double beta decay.

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.

Neutrino oscillation physics with a Neutrino Factory [PDF]

Proceedings of XXIst International Europhysics Conference on High Energy Physics — PoS(EPS-HEP2011), 2012
We illustrate that the baseline Neutrino Factory configuration being developed within the International Design Study for the Neutrino Factory (the IDS-NF) is optimized for standard oscillation-physics measurements and for searches for new physics. For small values of θ13 (sin2 2θ13 < 10−2 ) a Neutrino Factory with two storage rings in which 25 GeV ...
