Neutrino Observatories Can Characterize Cosmic Sources and Neutrino Properties

چکیده
Neutrino telescopes that measure relative fluxes of ultrahigh-energy νe, νμ, ντ can give information about the location and characteristics of sources, about neutrino mixing, and can test for neutrino instability and for departures from CPT invariance in the neutrino sector. We investigate consequences of neutrino mixing for the neutrino flux arriving at Earth, and consider how terrestrial measurements can characterize distant sources. We contrast mixtures that arise from neutrino oscillations with those signaling neutrino decays. We stress the importance of measuring νe, νμ, ντ fluxes in neutrino observatories.

متن کاملUltra-High Energy Cosmic Ray and Neutrino Observations
Recent measurements of ultra-high energy cosmic rays and neutrinos are reviewed. With several new large scale observatories nearing completion or becoming fully operational only very recently, a large body of high quality and high statistics data is growing up now. Already these first data have started to open up a new window to the high energy Universe giving us first direct clues about the or...
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 کاملNeutrino Properties from Measurements using Astrophysical and Terrestrial Sources
The current knowledge of neutrino properties has been derived from measurements performed with both astrophysical and terrestrial sources. Observations of neutrino flavor change have been made with neutrinos generated in the solar core, through cosmic ray interactions in the atmosphere and in nuclear reactors. A summary is presented of the current knowledge of neutrino properties and a descript...
متن کاملTopics in Neutrino Astrophysics
Part of the interest in neutrino astrophysics has to do with the fascinating interplay between nuclear and particle physics issues — e.g., whether neutrinos are massive and undergo flavor oscillations, whether they have detectable electromagnetic moments, etc. — and astrophysical phenomena, such as the clustering of matter on large scales, the mechanisms responsible for the synthesis of nuclei,...
