High Energy Neutrino and Tau Airshowers in Standard and New Physics

摘要

High Energy Neutrino may lead to a New High Energy Astronomy. Neutrinointeraction in matter at PeVs- EeVs may behave differently from Standard Modelpredictions because possible TeV Gravity scenario. While traditional km^3neutrino underground detector will be uneasy to disentangle the Gravity TeVscenario any new Horizontal Tau Air-Shower detectors at PeVs tau energy, beyondMountain Chains, will be greatly enhanced and it may probe fruit-fully the NewTeV Physics imprint. Moreover observing upcoming and horizontal tau air-showers{UPTAUS, HORTAUS} from high mountains toward Mount Chains or along widest EarthCrust crown masses at the Horizons edges, Ultra High Energy,UHE, nu_{tau} andits consequent tau lepton decay in flight, will greatly amplify any single UHEnu_{tau} track and it will test, at highest energies, huge volumes comparableto underground km^3 ones; observing UPTAUS and HORTAUs from higher balloons orsatellites at orbit altitudes, at GZK energies, the Horizontal Crown effectiveMasses may even exceed 150 km^3. These Highest energies (10^{19} eV) nuastronomy are tuned to test the needed abundant nu fluence in GZK Z-Showeringmodel: in this scenario ZeV Ultra High Energy neutrino are hitting on reliclight (0.1-5 eV masses) anti-neutrinos, clustered in dark hot halos, creatingUHE Z bosons whose decay in flight may be the hadronic secondaries observed onEarth atmosphere as UHECR, isotropically spread along the cosmic edges andclustered toward few correlated BL Lac sources.
