Query: Precision measurements and tau neutrino physics in a future accelerator
  neutrino experiment   We investigate prospects of building a future accelerator-based neutrino
oscillation experiment in China, including site selection, beam optimization
and tau neutrino physics aspects. CP violation, non-unitary mixing and
non-standard neutrino interactions are discussed. We simulate neutrino beam
setups based on muon and beta decay techniques and compare Chinese laboratory
sites by their expected sensitivities. A case study on Super Proton-Proton
Collider and China JinPing Laboratory is also presented. It is shown that the
muon-decay-based beam setup can measure the Dirac CP phase by about
14.2$^\circ$ precision at 1$\,\sigma$ CL, whereas non-unitarity can be probed
down to $|\alpha_{i j}| \lesssim$ 0.37 ($i \neq j =$ 1, 2, 3) and non-standard
interactions to $|\epsilon^m_{\ell \ell'}| \lesssim$ 0.11 ($\ell \neq \ell' =
e$, $\mu$, $\tau$) at 90% CL, respectively.
