Invisible Labor and the "Ghost Particle": Underground Physics at the Kolar Gold Fields. [PDF]
Ber WissAbstract 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.

Perspectives of Earth and Space Scientists, Volume 4, Issue 1, December 2023., 2023 Abstract My career has included astrophysics and space physics, always with a theoretical emphasis. My first papers calculated nuclear reaction rates in dense stars, particularly neutron stars, but I branched out to other areas or theoretical astrophysics.

Geophysical Research Letters, Volume 50, Issue 18, 28 September 2023., 2023 Abstract Despite being widely recognized, the importance of deep layers thermohaline and mixing processes in the ocean circulation and variability is still poorly investigated, especially in the Mediterranean Sea. This limits understanding and parametrizing deep dynamics, which result in evident biases in the global circulation representation by ...

Geophysical Research Letters, Volume 50, Issue 14, 28 July 2023., 2023 Abstract In this paper, we present the first high‐speed video observation of a cloud‐to‐ground lightning flash and its associated downward‐directed Terrestrial Gamma‐ray Flash (TGF). The optical emission of the event was observed by a high‐speed video camera running at 40,000 frames per second in conjunction with the Telescope Array Surface Detector ...

Library of Simulated Gamma‐Ray Glows and Application to Previous Airborne Observations
Journal of Geophysical Research: Atmospheres, Volume 128, Issue 9, 16 May 2023., 2023 Abstract Gamma‐Ray Glows (GRGs) are high energy radiation originating from thunderclouds, in the MeV energy regime, with typical duration of seconds to minutes, and sources extended over several to tens of square kilometers. GRGs have been observed from detectors placed on ground, inside aircraft and on balloons.

Sensitivity of a low threshold directional detector to CNO-cycle solar neutrinos
European Physical Journal C: Particles and Fields, 2018 A first measurement of neutrinos from the CNO fusion cycle in the Sun would allow a resolution to the current solar metallicity problem. Detection of these low-energy neutrinos requires a low-threshold detector, while discrimination from radioactive ...

Two-loop neutrino masses and the solar neutrino problem [PDF]
Physical Review D, 1994 The addition of $m$ singlet right-handed neutrinos to the Standard Model leads to radiatively generated mass corrections for the $SU(2)_L $ doublet neutrinos. For those neutrinos which are massless at the tree level after this addition, this implies a small mass generated at the two-loop level via $W^{\pm}$ exchange. We calculate these mass corrections

THE CHARGED NEUTRINO: A NEW APPROACH TO THE SOLAR NEUTRINO PROBLEM [PDF]
Modern Physics Letters A, 1994 We have considered the effect of the reduction of the solar neutrino flux on earth due to the deflection of the charged neutrino by the magnetic field of the solar convective zone. The antisymmetry of this magnetic field about the plane of the solar equator induces the anisotropy of the solar neutrino flux thus creating the deficit of the neutrino ...
