Description
Ultra-high-energy cosmic neutrinos have energies millions of times greater than any particle produced
on Earth. Traveling across the breadth of the observable Universe, they bring us unaltered information
from the most extreme astrophysical environments. However, because these particles are scarce and
interact with matter so rarely, detecting them requires specialized techniques. TAMBO (the Tau Air-
Shower Mountain-Based Observatory) is a proposed neutrino telescope, currently in pilot phase,
designed to probe a largely unexplored energy range (10^15 to 10^17 eV). While primarily optimized to
detect tau neutrinos, TAMBO also possesses a unique sensitivity to electron anti-neutrinos within a
specific, narrow energy window. Measuring the relative abundance of these different neutrino types---
their "flavor composition"---provides a powerful test for both extreme astrophysical models and
fundamental physics. In this study, we use advanced detector simulations to evaluate the capacity of
TAMBO to identify these electron anti-neutrinos. We report, for the first time, how precisely TAMBO
could measure neutrino flavor composition at these unprecedented energies, benchmarking its
upcoming science reach.
