Description

We present the results of three searches for correlations between UHECR events measured by the Pierre Auger Observatory and Telescope Array and high energy neutrino candidate events from IceCube and ANTARES. A cross-correlation analysis is performed, where the angular separation between the arrival directions of UHECRs and neutrinos is scanned. The same events are also exploited in a separate search by stacking the neutrino arrival directions: a maximum likelihood approach is used where a modelling of magnetic deflections of UHECRs is included and accounted for. Finally, a similar analysis is performed on stacked UHECR arrival directions and the IceCube and ANTARES samples of through-going muon-track events that were optimised for neutrino point source searches.
