Abstract
We propose to use existing LHAASO detectors to study of the flavor composition of UHE astrophysical neutrino. Monte Carlo simulations show that large Water Cherenkov Detector Array (WCDA) is a suitable detector to record high energy near horizontal neutrino interactions, due to its cell structure and rather large size. Signature of such events is very clear thus allows us even to determine the neutrino flavor interacting in the WCDA. The mass of this detector is about 300 kt of water and it is not enough to accumulate many high-energy neutrino events in a near future. Nevertheless, it is running detector and we could develop suitable algorithms for this program and make a search for these events regarding WCDA as a prototype for future full-scale experiment. Moreover, existing of square km EAS array (Km2A) with many muon detectors makes it possible to have a powerful veto against a background flux of near-horizontal atmospheric muons.
期刊介绍：
Physics of Atomic Nuclei is a journal that covers experimental and theoretical studies of nuclear physics: nuclear structure, spectra, and properties; radiation, fission, and nuclear reactions induced by photons, leptons, hadrons, and nuclei; fundamental interactions and symmetries; hadrons (with light, strange, charm, and bottom quarks); particle collisions at high and superhigh energies; gauge and unified quantum field theories, quark models, supersymmetry and supergravity, astrophysics and cosmology.
