We consider charged Higgs and W%26apos; gauge boson contributions to the quasielastic scattering nu(tau) + n -%26gt; tau(-) + p and (nu(tau)) over bar and + p -%26gt; 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.
