Abstract
A search for angular correlations between high-energy neutrinos detected by ANTARES and the cosmic rays events measured by the Pierre Auger Observatory and the Telescope Array experiments is presented. An unbinned likelihood-ratio method is used, using both the angular information an energy estimation of the reconstructed neutrinos. The search has been applied to the nine-years ANTARES all-flavour point-source sample, leading to a non significant correlation. A $90\%$ upper limit on the flux emitted by the candidate neutrino sources associated to the cosmic ray population is reported: $\Phi^\mathrm{UL}_\mathrm{tot}=1.5 \, 10^{-7}$ GeV$^{-1}$cm$^{-2{}}$s$^{-1}$.
