D.Fargion
- On the rumors of the premature Z-model death
which is and it remains unique to solve the
homogeneity and isotropy puzzle in UHECR data - Z-Burst UpDated (2006)

8Nearest AGN Jet , M87, is not in UHECR list and
is not pointing to us

15The real puzzle in UHECRis the absence of local

versus Neutrino does we face non-degenerated
neutrino masses?
24Z-Burst UpdatedIs the Neutrino mass degenerate
or not?
- The prenent neutrino mass cosmic bounds by
W-map - are favouring lighter and lighter neutrino,
- leading from nearly degenerated neutrino masses
(mn 0.4 eV or 0.15 eV) to eventual NON
degenerated neutrino masses for future bounds
(Sum masses lt 0.15 eV) - For example twin
- (mn1 0.1 eV, mn2 0.05 eV , mn3 0.045)
or triple - (mn1 0.06 eV, mn2 0.008 eV , mn3 0.0001
eV)

29Conclusions
- The Tens EeV UHECR must trace in gamma their
arrival if UHECR direct proton (billions year
flight) - The Z-Shower events occuring inside 10 Mpcs
- (nearly GZK ) volumes of hot lightest
neutrinos , are not polluted by secondary gamma
and TeV (Tinyakov 2004) traces (unobserved). - The Forte experiment actually is observing 3
events not a real limit (yet) on Z Model. - Z-Burst is the only one making BL-Lac at z
0.5 - related to UHECR Isotropy in AGASA, HIRES
and AUGER still favour cosmic connection, and
Z-Showering is the unique to courier their
energy.
