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...

A search for cosmic neutrino sources using the data collected with ANTARES telescope between early 2007 and end of 2015 is performed. For first time, all interactions---charged- neutral-current interactions flavors---are considered in a point-like detector. In previous analyses, only muon charged-current were used. This achieved by novel reconstruction algorithm shower-like events addition to standard track reconstruction. The shower channel contributes about 23% signal an...
The ANTARES detector is at present the most sensitive neutrino telescope in Northern Hemisphere. highly significant cosmic excess observed by Antarctic IceCube can be studied with ANTARES, exploiting its complementing field of view, exposure, and lower energy threshold.

This work includes first time both track-like (mainly...
Neutrino detectors participate in the indirect search for fundamental constituents of dark matter (DM) form weakly interacting massive particles (WIMPs). In WIMP scenarios, candidate DM can pair-annihilate into Standard Model products, yielding considerable fluxes high-energy neutrinos. A detector like ANTARES, located Northern Hemisphere, is able to perform a competitive looking towards Galactic Centre, where high density thought accumulate. Both this directional information and spectral...

The existence of diffuse Galactic neutrino production is expected from cosmic ray interactions with gas and radiation fields. Thus, neutrinos are a unique messenger offering the opportunity to test products up energies hundreds TeV. Here we present search for this using ten years ANTARES track shower data, as well seven IceCube data. data combined into joint likelihood emission according KRA$_\gamma$ model assuming 5 PeV per nucleon cutoff. No significant excess found. As consequence, limits...

In the past decade, a new class of bright transient radio sources with millisecond duration has been discovered. The origin these so-called Fast Radio Bursts (FRBs) is still great mystery despite growing observational efforts made by various multi-wavelength and multi-messenger facilities. So far, many models have proposed to explain FRBs but neither progenitors nor radiative particle acceleration processes at work clearly identified. this paper, question whether some hadronic may occur in...
