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