Description
Ultra-high energy neutrinos (>10^16 GeV) are expected to be produced through cosmic-ray interactions with the Cosmic Microwave Background (CMB). This so-called cosmogenic flux of UHE neutrinos is a target of the next generation neutrino observatories: IceCube-Gen2, TAMBO, RNOG, GRAND, POEMMA, and CHANT. Many of these detectors rely on measuring the neutrino interaction either directly at the vertex, or through its charged particle counterpart's electromagnetic or decay shower. A new technique has also been put forward which relies on the observation of Earth-throughgoing tau neutrinos at PeV energies. By measuring the tau neutrino flux at this energy, one can indirectly observe the flux at the EeV scale since these two are related by the cascading down of tau neutrinos through the process of tau regeneration. These ideas demand an accurate simulation of UHE neutrino transport. In this contribution we present TauRunner, a Python Monte Carlo (MC) package specialized in UHE neutrino transport. We present new functionalities, including the incorporations of all neutrino flavors in the propagation and significant performance imrovements enabling an efficient and accurate simulation of neutrino propagation through any media.
