Neutrino Unification [PDF]

Physical Review Letters, 2001
Present neutrino data are consistent with neutrino masses arising from a common seed at some ``neutrino unification'' scale $M_X$. Such a simple theoretical ansatz naturally leads to quasi-degenerate neutrinos that could lie in the electron-volt range ...

Sterile Neutrinos with Neutrino Telescopes [PDF]

Universe, 2021
Searches for light sterile neutrinos are motivated by the unexpected observation of an electron neutrino appearance in short-baseline experiments, such as the Liquid Scintillator Neutrino Detector (LSND) and the Mini Booster Neutrino Experiment (MiniBooNE). In light of these unexpected results, a campaign using natural and anthropogenic sources to find

Neutrinos [PDF]

Proceedings of the National Academy of Sciences, 1999
Neutrinos represent a new “window” to the Universe, spanning a large range of energy. We discuss the science of neutrino astrophysics and focus on two energy regimes. At “lower” energies (≈1 MeV), studies of neutrinos born inside the sun, or produced in interactions of cosmic rays with the atmosphere, have allowed the first incontrovertible evidence ...

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.

Reconciling present neutrino puzzles: Sterile neutrinos as mirror neutrinos [PDF]

Physical Review D, 1995
We suggest that recent neutrino puzzles that are the solar and atmospheric neutrino deficits as well as the possible neutrino oscillations reported by the LSND experiment and the possibility of massive neutrinos providing the hot component of the cosmological dark matter, can all be naturally explained by assuming existence of a mirror world described ...

Neutrino velocity and neutrino oscillations [PDF]

Physical Review D, 2012
We study distances of propagation and the group velocities of the muon neutrinos in the presence of mixing and oscillations assuming that Lorentz invariance holds. Oscillations lead to distortion of the $ _ $ wave packet which, in turn, changes the group velocity and the distance $ _ $ travels. We find that the change of the distance, $d_{osc}$, is

Neutrino decay and atmospheric neutrinos [PDF]

Physics Letters B, 1999
We reconsider neutrino decay as an explanation for atmospheric neutrino observations. We show that if the mass-difference relevant to the two mixed states _ and _ is very small (< 10^{-4} eV^2), then a very good fit to the observations can be obtained with decay of a component of _ to a sterile neutrino and a Majoron. We discuss how the K2K

Neutrino-antineutrino transitions [PDF]

Physical Review D, 1998
We consider transitions between neutrinos and anti-neutrinos in laboratory experiments in five scenarios, including both helicity flipping and preserving cases.

The Spectrum of Light Emitted by LED Using a CMOS Sensor-Based Digital Camera and Its Application

Sensors, 2022
We introduced a digital photo image analysis in color space to estimate the spectrum of fluor components dissolved in a liquid scintillator sample through the hue and wavelength relationship.

Image Reconstruction and Investigation of Factors Affecting the Hue and Wavelength Relation Using Different Interpolation Algorithms with Raw Data from a CMOS Sensor

Photonics, 2023
An image processing method was employed to obtain wavelength information using light irradiated during camera exposure. Physically, hue (H) and wavelength (W) are closely related. Once the H value is known through image pixel analysis, the wavelength can
