The KM3NeT Collaboration aims at the construction of the next-generation large-volume neutrino telescope in the Mediterraean Sea.
The planned KM3NeT/ARCA detector will allow the detailed study of cosmic neutrinos both in point-source and in diffuse-flux mode. The foreseen performance in searches for cosmic neutrinos have been reported in the KM3NeT Letter of Intent.
Thanks to the use of more sophisticated analysis methods and to the development of a new track reconstruction algorithm, new estimates of the detection capabilities of the ARCA detector for a diffuse flux of neutrinos originating from the whole sky and from a selected region covering the central part Galactic Plane are reported.
The detection capability of the detector has been estimated analyzing both the cascade and track channels.
