Measurement of the atmospheric νμ flux with six detection units of KM3NeT/ORCA
article
A measurement of the atmospheric νμ + ¯νμ flux with energies between 1 and 100 GeV is presented. Themeasurement has been performed using data taken with the first six detection units of the KM3NeT/ORCA detector, referred to as ORCA6. The datawere collected between January 2020 and November 2021 and correspond to 510 days of livetime, with a total exposure of 433 kton·years. Usingmachine learning classification, 3894 neutrino candidate events have been selected with an atmospheric muon contamination of less than 1%. The atmospheric νμ+¯νμ energy spectrum is derived using an unfolding procedure and the impact of systematic uncertainties is estimated. The atmospheric νμ+¯νμ flux measured using the ORCA6 configuration is in agreement with the values measured by other experiments.
