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

Ber Wiss
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.

Neutrino tomography of the Earth with ORCA detector

European Physical Journal C: Particles and Fields, 2022
Using PREM as a reference model for the Earth density distribution we investigate the sensitivity of ORCA detector to deviations of the Earth (i) outer core (OC) density, (ii) inner core (IC) density, (iii) total core density, and (iv) mantle density ...

A flavor-inspired radiative neutrino mass model

Journal of High Energy Physics, 2022
One of the most important discoveries in particle physics is the observation of nonzero neutrino masses, which dictates that the Standard Model (SM) is incomplete.

Tau neutrinos in IceCube, KM3NeT and the Pierre Auger Observatory

SciPost Physics Proceedings, 2019
In 2018, the IceCube collaboration reported evidence for the identification of a blazar as an astrophysical neutrino source. That evidence is briefly summarised here before focusing on the prospects of tau neutrino physics in IceCube, both at high ...

The Use of Low Temperature Detectors for Direct Measurements of the Mass of the Electron Neutrino

Advances in High Energy Physics, 2016
Recent years have witnessed many exciting breakthroughs in neutrino physics. The detection of neutrino oscillations has proved that neutrinos are massive particles, but the assessment of their absolute mass scale is still an outstanding challenge in ...

B-decay anomalies and scalar leptoquarks in unified Pati-Salam models from noncommutative geometry

Journal of High Energy Physics, 2018
Motivated by possible scalar-leptoquark explanations of the recently reported B-decay anomalies, we investigate whether the required leptoquarks can be accommodated within models based on noncommutative geometry (NCG).

Constraints on new physics from $$K \rightarrow \pi \nu {\bar{\nu }}$$ K→πνν¯

European Physical Journal C: Particles and Fields, 2018
We study generic effects of new physics on the rare decay modes $$K_L \rightarrow \pi ^0 \nu {\bar{\nu }}$$ KL→π0νν¯ and $$K^+ \rightarrow \pi ^+ \nu {\bar{\nu }}$$ K+→π+νν¯ .

How broad is a neutrino?

Journal of High Energy Physics, 2023
Canonical neutrino oscillations arise due to the propagation of three mass eigenstates from production to detection. We aspire to capture, in one simple framework, a broad range of new physics effects on neutrino propagation beyond this canonical picture

Neutrinos in a Minimal 3-3-1 Model

Frontiers in Physics, 2022
In this work, we present a general review of neutrino physics in the minimal 331 model. New gauge and scalar interactions are present, with violation of both flavor and lepton numbers.

Neutrino amplitude decomposition: toward observing the atmospheric-solar wave interference

European Physical Journal C: Particles and Fields, 2020
Observation of the interference between the atmospheric and solar oscillation waves with the correct magnitude would provide another manifestation of the three-generation structure of leptons.
