AbstraktAbstract
On February 13, 2023, the KM3NeT/ARCA neutrino telescope detected an ultra-high-energy neutrino event, KM3-230213A, with an estimated energy of approximately 220 PeV - the most energetic neutrino ever observed. This unprecedented event marks a significant milestone in the field of astroparticle physics, offering new insights into the potential sources of these extreme astrophysical phenomena. In this work, we present a follow-up analysis aimed at identifying a potential cosmic point-like neutrino source associated with KM3-230213A. We perform a dedicated search for a cluster of neutrino events in the direction of KM3-230213A using data from KM3NeT/ARCA, KM3NeT/ORCA, ANTARES and IceCube. In order to assess the potential spatial clustering of neutrino events around KM3-230213A, we employ either an ON/OFF technique or a maximum-likelihood method. This contribution presents the methodology, the datasets used, the event selection criteria, and the statistical methods applied. We discuss the results in the context of multi-messenger astrophysics, highlighting their implications for the origin of the ultra-high-energy neutrino KM3-230213A.
