Event reconstruction and neutrino selection with KM3NeT/ARCA230

The discovery of high-energy cosmic neutrinos has raised great interest in the field of neutrino astronomy. The KM3NeT/ARCA detector is currently under construction at the bottom of the Mediterranean Sea and is measuring high-energy neutrinos. The complete detector will instrument a cubic kilometre of seawater with photomultiplier tubes that detect the Cherenkov radiation from the products of neutrino interactions. The design is focused on discovering high-energy neutrino sources which requires an excellent angular resolution. This contribution covers the reconstruction algorithms deployed in the full KM3NeT/ARCA detector and their performances. The angular resolution reaches below 0.1∘ for tracks and below 1∘ for cascades and double cascades that originate from tau neutrinos. Additionally, the neutrino selections for the full KM3NeT/ARCA diffuse and point source studies are covered.
