Comparison of the measured atmospheric muon flux with Monte Carlo simulations for the first KM3NeT/ARCA and KM3NeT/ORCA Detection Units

Not scheduled


Mr Piotr Kalaczynski (NCBJ Warsaw)


The KM3NeT Collaboration has successfully
deployed the first detection units in the Mediterranean
Sea in 2016 and 2017 at the two sites in Italy and in France. The sample of data collected between
December 2016 and January 2020 has been used to measure the atmospheric muon flux at two
differen t depths under the sea level: 3.5 km with ARCA and 2.5 km with ORCA. The atmospheric
muon flux represents an abundant signal for a neutrino telescope and can be used to test the reliability
of the Monte Carlo simulation chain. In this contribution the mea surements are compared to Monte
Carlo simulations based mainly on MUPAGE and CORSIKA codes. The main features of the
simulation and reconstruction chain are discussed and presented in the poster.
