Query: Nonstandard interactions of tau neutrino via charged Higgs and $W'$
  contribution   We consider charged Higgs and $W'$ gauge boson contributions to the
quasielastic scattering $\nu_{\tau}+ n \rightarrow \tau^- + p$ and
$\bar{\nu}_{\tau}+ p \rightarrow \tau^+ + n$ . These effects modify the
standard model cross section for these processes and thus impact the extraction
of the neutrino mixing angles $\theta_{23}$ and $\theta_{13}$ . We include form
factor effects in our calculations and find the deviation of the actual mixing
angle from the measured one, assuming the standard model cross section, can be
significant and can depend on the energy of the neutrino.
