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

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 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.

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 with neutrino mass splittings induced by renormalization effects associated with supersymmetric ...

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.

Borexino Results on Neutrinos from the Sun and Earth
Universe, 2021 Borexino is a 280-ton liquid scintillator detector located at the Laboratori Nazionali del Gran Sasso in Italy. Since the start of its data-taking in May 2007, it has provided several measurements of low-energy neutrinos from various sources. At the base

Multimessenger Astronomy with Neutrinos
Universe, 2021 Multimessenger astronomy is arguably the branch of the astroparticle physics field that has seen the most significant developments in recent years. In this manuscript, we will review the state-of-the-art, the recent observations, and the prospects and ...
