Studies of primary mass sensitivity of muons of the IceCube surface array IceTop — •Donghwa Kang for the IceCube collaboration — Karlsruhe Institute of Technology

The surface component of the IceCube Neutrino Observatory at the geographical South Pole, IceTop, is designed to measure the air showers of cosmic ray with energies from PeV to EeV. Based on the charge signal distribution only with IceTop, a mass-sensitive parameter was defined and estimated event by event, which is the sum of the charge signals divided by the effective area at a fixed distance from the shower core. In this contribution the estimated mass-sensitive parameter and its dependencies on the hadronic interaction models will be discussed.
