Current Status of Simulation for the Tau Air-Shower Mountain-Based Observatory

While IceCube’s detection astrophysical neutrinos at energies up to a few PeV has opened a new window to our Universe, much remains to be discovered regarding these neutrinos’ origin and nature. In particular, the difficulty differentiating ν_e and ν_τ charged-current (CC) events in the energy limits our ability to measure precisely the flavor ratio of this flux. The Tau Air-Shower Mountain-Based Observatory (TAMBO) is a next-generation neutrino observatory capable of producing a high-purity sample of ν_τ CC events in the energy range from 1-100 PeV, i.e. just above the IceCube measurements. An array of water Cherenkov tanks and plastic scintillators deployed on one face of the Colca Canyon will observe the air-shower produced when a τ lepton, produced in a ν_τ CC interaction, emerges from the opposite face and decays in the air. In this contribution, I will present the current status of the TAMBO simulation, including preliminary sensitivities to various flux models.
