For several decades, the origin of ultra-high-energy cosmic rays (UHECRs) has been an unsolved question of highenergy
astrophysics. One approach for solving this puzzle is to correlate UHECRs with high-energy neutrinos,
since neutrinos are a direct probe of hadronic interactions of cosmic rays and are not deflected by magnetic fields.
In this paper, we present three different approaches for correlating the arrival directions of neutrinos with the
arrival directions of UHECRs. The neutrino data are provided by the IceCube Neutrino Observatory and
ANTARES, while the UHECR data with energies above ∼50 EeV are provided by the Pierre Auger Observatory
and the Telescope Array. All experiments provide increased statistics and improved reconstructions with respect to
our previous results reported in 2015. The first analysis uses a high-statistics neutrino sample optimized for pointsource
searches to search for excesses of neutrino clustering in the vicinity of UHECR directions. The second
analysis searches for an excess of UHECRs in the direction of the highest-energy neutrinos. The third analysis
searches for an excess of pairs of UHECRs and highest-energy neutrinos on different angular scales. None of the analyses have found a significant excess, and previously reported overfluctuations are reduced in significance.
Based on these results, we further constrain the neutrino flux spatially correlated with UHECRs.
