Description
Measuring the radial density profile of the Earth by observing absorption of neutrino has been discussed more than 40 years as a unique complemental method of body-wave studies based on seismic wave measurement. In this study, we use neutrino track events arriving to the IceCube neutrino observatory at the South Pole from the northern hemisphere and compare the fluxes of atmospheric and cosmic neutrinos between at the Earth’s surface and at the detector. We assume various concentric layered structure in density profile of the Earth and calculated absorption probability using nuFATE program for each density model. The 13 years of IceCube data collected from 2010 to 2022 will be then compared with the data. We present the analysis method and 10% of 12 years data compared with our prediction.
