The main objectives of the KM3NeT Collaboration are (i) discovery and subsequent observation high-energy neutrino sources in Universe (ii) determination mass hierarchy neutrinos. These strongly motivated by two recent important discoveries, namely: (1) astrophysical signal reported IceCube (2) sizable contribution electron neutrinos to third eigenstate as Daya Bay, Reno others. To meet these objectives, plans build a new Research Infrastructure consisting network deep-sea telescopes...
