Extremely High Energy Neutrinos and Their Detection
We discuss in some detail the production of extremely high energy (EHE) neutrinos with energies above 1018 eV. The most certain process for producing such neutrinos results from photopion production by EHE cosmic rays in the cosmic background photon Ðeld. However, using assumptions for the EHE cosmic-ray source evolution that are consistent with results from the deep QSO survey in the radio and...
متن کاملExtremely High Energy Cosmic Neutrinos and Relic Neutrinos
I review the essentials of ultrahigh-energy neutrino interactions, show how neutral-current detection and flavor tagging can enhance the scientific potential of neutrino telescopes, and sketch new studies on neutrino encounters with dark matter relics and on gravitational lensing of neutrinos. 1. Neutrino Observatories: Expectations An early goal of the next generation of neutrino telescopes wi...
متن کاملProbing Neutrino Dark Energy with Extremely High-Energy Cosmic Neutrinos
Recently, a new non-Standard Model neutrino interaction mediated by a light scalar field was proposed, which renders the big-bang relic neutrinos of the cosmic neutrino background a natural dark energy candidate, the so-called Neutrino Dark Energy. As a further consequence of this interaction, the neutrino masses become functions of the neutrino energy densities and are thus promoted to dynamic...
متن کاملHigh Energy Cosmic Neutrinos
While the general principles of high-energy neutrino detection have been understood for many years, the deep, remote geographical locations of suitable detector sites have challenged the ingenuity of experimentalists, who have confronted unusual deployment, calibration, and robustness issues. Two high energy neutrino programs are now operating (Baikal and AMANDA), with the expectation of usheri...
متن کاملHigh energy astrophysical neutrinos
High energy neutrinos with energy typically greater than tens of thousands of GeV may originate from several astrophysical sources. The sources may include, for instance, our galaxy, the active centers of nearby galaxies, as well as possibly the distant sites of gamma ray bursts. I briefly review some aspects of production and propagation as well as prospects for observations of these high ener...
