The absence of semitauonic decays of charmed hadrons makes the decayprocesses mediated by the quark-level $c\to d \tau^+ \nu_{\tau}$ transitioninadequate for probing a generic new physics (NP) with all kinds of Diracstructures. To fill in this gap, we consider in this paper the quasielasticneutrino scattering process $\nu_{\tau}+n\to \tau^-+\Lambda_c$, and proposesearching for NP through the polarizations of the $\tau$ lepton and the$\Lambda_c$ baryon. In the framework of a general low-energy effectiveLagrangian, we perform a comprehensive analysis of the (differential) crosssections and polarization vectors of the process both within the Standard Modeland in various NP scenarios, and scrutinize possible NP signals. We alsoexplore the influence on our findings due to the uncertainties and thedifferent parametrizations of the $\Lambda_c \to N$ transition form factors,and show that they have become one of the major challenges to further constrainpossible NP through the quasielastic scattering process.
