Splitting Neutrino masses and Showering into Sky

Abstract

Neutrino masses might be as light as a few time the atmospheric neutrino mass splitting. The relic cosmic neutrinos may cluster in wide Dark Hot Local Group Halo. High Energy ZeV cosmic neutrinos (in Z-Showering model) might hit relic ones at each mass in different resonance energies in our nearby Universe. This nondegenerated density and energy must split UHE Z-boson secondaries (in Z-Burst model) leading to multi injection of UHECR nucleons within future extreme AUGER energy. Secondaries of Z-Burst as neutral gamma, below a few tens EeV are better surviving local GZK cut-off and they might explain recent Hires BL-Lac UHECR correlations at small angles. A different high energy resonance must lead to Glashow's anti-neutrino showers while hitting electrons in matter. In water and ice it leads to isotropic light explosions. In air, Glashow's antineutrino showers lead to collimated and directional air-showers offering a new Neutrino Astronomy. Because of neutrino flavor mixing, astrophysical energetic tau neutrino above tens GeV must arise over atmospheric background. At TeV range is difficult to disentangle tau neutrinos from other atmospheric flavors. At greater energy around PeV, Tau escaping mountains and Earth and decaying in flight are effectively showering in air sky. These Horizontal showering is splitting by geomagnetic field in forked shapes. Such air-showers secondaries release amplified and beamed gamma bursts (like observed TGF), made also by muon and electron pair bundles, with their accompanying rich Cherenkov flashes. Also planet's largest (Saturn, Jupiter) atmosphere limbs offer an ideal screen for UHE GZK and Z-burst tau neutrino, because their largest sizes. Titan thick atmosphere and small radius are optimal for discovering up-going resonant Glashow resonant anti-neutrino electron showers. Detection from Earth of Tau, anti-Tau, anti-electron neutrino induced Air-showers by twin Magic Telescopes on top mountains, or space based detection on balloons and satellites arrays facing the atmosphere's limbs are the simplest and cheapest way toward UHE Neutrino Astronomy Horizons.

Where are the Ultra High Energy Cosmic Ray (UHECR) originated?

“…In the same section we also discuss the case of an unexplained clustering correlated to a half cosmic radius 1 far source: 3C454. We proposed [9] and confirm here that this clustering, if growing (as it is) and being confirmed, might be associated and originated by a far beamed AGN, whose ZeV neutrino are scattering onto a relic cosmic neutrino background (with 1 − 2eV mass) via Z boson resonance (the so called Z burst model) [10][11][12][13]. Indeed the UHE ZeV neutrinos, emitted by far AGN do not interact with the cosmic photons and do not suffer of a GZK cutoff.…”

“…Such a far source (3C 454) is near 2.5 Giga-parsec distance, almost 50 times above the most penetrating proton UHECR (and almost thousand times the GZK He survival distance): there is no way to reach directly to us overcoming the exponential ( e −50 ) GZK cutoff. Therefore, the possible role of a relic mass neutrino of nearly one eV mass may play the role of a calorimeter able to capture a different courier (a ZeV anti-neutrino) in order to explain this puzzling connection [10], [11]. More in detail the AGN may shine UHECR also at ZeV energies for neutrinos that cross the Universe with negligible absorption and hit in a wide relic neutrino mass halo (several or tens Mpc wide) making a Z boson: such forming UHE Z resonance, its decay in hadrons (involving nucleon-antinucleon pairs) is the final UHECR message to us.…”

Solar neutrino flare, megaton neutrino detectors and human space journey

“…The whole muon anti-neutrino electron (comparable to the anti neutrino muon and tau ones) spectra with the main solar neutrino component almost absent. The upward and downward atmospheric muon neutrinos would show the suppression of factor half due to average mixing into the tau flavor 14,15 . The absence of solar neutrino noise makes antineutrino detection an ideal tool to disentangle the solar flare signal.…”

A shell like kilometer spaced array or a honey comb one around Icecube

“…Incidentally the presence of UHECR anisotropy and the few hot spot was also suggesting an eventual connection between the UHE neutrino clustering and the new born correlation with eventual UHECR spot. The earliest far clustering of far redshift UHECR were also suggestive to be relic trace of cosmic, dark neutrino mass halo hit by ZeV neutrinos [10], [9]. This search of ν and UHECR connection at the moment it is not yet conclusive [11], [12].…”

“…Anyway a different and more clean neutrino astronomy may rise soon by tau air-showers, considered since more than two decades [3]., from mountains [4] or valleys, from ground or space [5,6] ,and searched in more details [7] in different ways in space [8] and on Earth [4]. The airshower by upward tau neutrino may shine at such altitudes where the geomagnetic bending play relevant role, [9]. Therefore future setection need peculiar vertical or crown arrays.…”
