Description
KM3NeT/ORCA is a neutrino telescope currently under construction in
the Mediterranean Sea near Toulon, France. Its ultimate goal is the
determination of the neutrino mass ordering based on several years of
data taking with an instrumented seawater mass of about 7 Mton. From
January 2020 until November 2020 KM3NeT/ORCA accumulated data
with six detection units, which corresponds to about 3% of its envisaged
final size. From these data a clean sample of more than thousand
atmospheric neutrinos has been extracted.
This contribution recalls the potential of the complete KM3NeT/ORCA detector to determine the neutrino mass ordering, to constrain the normalisation of the tau-neutrino flux and to measure the oscillation parameters θ23 and Δm312. Further, a first measurement of these parameters from early data from KM3NeT/ORCA will be presented.
