Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields**

open access: yesBerichte zur Wissenschaftsgeschichte, Volume 48, Issue 1-2, Page 163-179, August 2025.
Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.

Two Micron‐Size Dark Dimensions

open access: yesFortschritte 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.

Final results of nu-e-bar electron scattering cross-section measurements and constraints on new physics

open access: yes, 2012
The nu-e-bar electron elastic scattering cross-section was measured with a CsI(Tl) scintillating crystal detector array with a total mass of 187 kg at the Kuo-Sheng Nuclear Power Station. The detectors were exposed to a reactor nu-e-bar flux of 6.4 X 10^{

Neutrino Masses [PDF]

open access: yes, 1994
This is a review for Reports of Progress in Physics. After an introduction we start by explaining the different neutrino masses corresponding to different types of neutrinos, Dirac or Majorana, in section 2.

Polarimetric Wide‐Angle Radar Detects Competing Signatures of Ice Fabric and Structural Firn Anisotropy

open access: yesGeophysical 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.

Solar neutrinos and the strongest oscillation constraints on scalar NSI

open access: yesJournal of High Energy Physics
Scalar non-standard neutrino interactions (sNSI) is a scenario where neutrinos can develop a medium dependent contribution to their mass due to a new scalar mediator.

On the photon–classical electromagnetic field relationship

open access: yesAnnals 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

IceCube Non-detection of GRBs: Constraints on the Fireball Properties

open access: yes, 2012
The increasingly deep limit on the neutrino emission from gamma-ray bursts (GRBs) with IceCube observations has reached the level that could put useful constraints on the fireball properties.

Is there evidence for additional neutrino species from cosmology? [PDF]

open access: yes, 2017
It has been suggested that recent cosmological and flavor-oscillation data favor the existence of additional neutrino species beyond the three predicted by the Standard Model of particle physics.

Non-standard neutrino interactions mediated by a light scalar at DUNE

open access: yesJournal of High Energy Physics
We investigate the effect on neutrino oscillations generated by beyond-the-standard-model interactions between neutrinos and matter. Specifically, we focus on scalar-mediated non-standard interactions (NSI) whose impact fundamentally differs from that of
