The impact of the mass composition of ultra-high-energy cosmic rays on the correlation with high-energy neutrinos — •Philipp Muth, Christian Haack, Saskia Philippen, Rene Reimann, Lisa Schumacher, and Christopher Wiebusch for the IceCube collaboration — III. Physikalisches Institut B, RWTH Aachen

The search for sources of highly energetic cosmic messengers such as ultra-high-energy cosmic rays (UHECRs) with an energy above several EeV and cosmic neutrinos is an active field of research as these sources have remained unidentified to date. UHECRs and neutrinos are suspected to share common sources, which motivates a multi-messenger approach correlating the data from different experiments. UHECRs, unlike neutrinos, are deflected by magnetic fields depending on their rigidity, and this deflection has to be accounted for when searching for these common sources. While no quantitative consensus on the mass composition of UHECRs at the EeV-range has been reached, assumptions on the resulting rigidities need to be assessed. In this talk, the impact of the UHECR mass composition on a correlation analysis of UHECR and neutrino data will be discussed.
