A Simulation Model for Solar Atmopheric Neutrinos — •Kruteesh Desai and Stephan Meighen-Berger — TU München, Müunchen, Deutschland

We introduce a new Solar Atmospheric Neutrino Simulation Model. Solar atmospheric neutrinos are produced in cascades initiated by cosmic rays in the solar atmosphere. The model is based on the principles of cascade equations, widely studied for Earth's atmosphere. This provides a flexible environment to study the impact of solar, primary, and interaction models. The simulation model includes all relevant particles for the production of neutrinos, with the option to extend to other interacting particles. This could in turn be applied to the study of neutrinos produced due to dark matter. The Solar model used here is based on Helioseismic observations from the GOLF instrument onboard the SOHO satellite. This allows differentiating between fluxes generated in low and high impact parameter scenarios. These fluxes are expected to differ due to the rapidly varying density profile of the Sun. We present the different components of the simulation model and the resulting neutrino fluxes, as well as example applications for experiments, such as IceCube.
