Query: Tau Neutrinos with Cherenkov Telescope Array   The next generation of Imaging Atmospheric Cherenkov telescope, like CTA, is
going to strongly improve the detection capability of high-energy cosmic rays.
In our paper we discuss the possibility to use such apparatus to detect
Earth-skimming tau neutrinos. Interestingly the analysis shows that order few
events per year can be detected for energies above $10^8$ GeV in the optimistic
case of larger neutrino fluxes produced by Flat Spectrum Radio Quasars.
However, even for more conservative cosmogenic neutrino fluxes such rate will
be also obtained, but for a decade of running. This estimate seems to candidate
a set up like CTA for performing high energy neutrino astronomy as well.
