摘要：

The absence of semitauonic decays of charmed hadrons makes the decay processes mediated by the quark-level c -> d tau thorn nu tau transition inadequate for probing a generic new physics (NP) with all kinds of Dirac structures. To fill in this gap, we consider in this paper the quasielastic neutrino scattering process nu tau thorn n -> tau- thorn Lambda c, and propose searching for NP through the polarizations of the tau lepton and the Lambda c baryon. In the framework of a general low-energy effective Lagrangian, we perform a comprehensive analysis of the (differential) cross sections and pol...
