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

, 2001 A revolution in our understanding of the neutrino sector is underway, driven by observations that are interpreted in terms of changes in neutrino flavors as they propagate. Since neutrino oscillations occur only if neutrinos are massive, these phenomena indicate physics beyond the Standard Model.

Neutrino Mixing from CP Symmetry [PDF]
, 2015 The neutrino mass matrix has remnant CP symmetry expressed in terms of the lepton mixing matrix, and vice versa the remnant CP transformations allow us to reconstruct the mixing matrix.

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.

Long baseline neutrino oscillation experiments with accelerators in Japan
European Physical Journal C: Particles and Fields, 2020 The development of long baseline neutrino oscillation experiments with accelerators in Japan is reviewed. Accelerator experiments can optimize experimental conditions, such as the beam and the detector, as needed.

Cobimaximal mixing with Dirac neutrinos
Physics Letters B, 2021 If neutrinos are Dirac, the conditions for cobimaximal mixing, i.e. θ23=π/4 and δCP=±π/2 in the 3×3 neutrino mixing matrix, are derived. One example with A4 symmetry and radiative Dirac neutrino masses is presented.

Renormalisation group corrections to neutrino mixing sum rules [PDF]
, 2015 A bstractNeutrino mixing sum rules are common to a large class of models based on the (discrete) symmetry approach to lepton flavour. In this approach the neutrino mixing matrix U is assumed to have an underlying approximate symmetry form Ũν, which is ...

Updated fit to three neutrino mixing: status of leptonic CP violation [PDF]
Journal of High Energy Physics, 2014 We present a global analysis of solar, atmospheric, reactor and accelerator neutrino data in the framework of three-neutrino oscillations based on data available in summer 2014.

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.
