Abstract
We present perspectives for searching for light dark matter production mediated by a leptophilic scalar $\ensuremath{\phi}$ and a dark photon ${A}^{\ensuremath{'}}$ in experiments at a super c-tau factory. Based on the analysis of the associative production of mediators and $\ensuremath{\tau}$-leptons at the energies of a future collider, the possibility of searching in the nonexcluded region of the parameter space was found. The obtained sensitivity curves at the 90% C.L. for the mediators' mass range below 4 GeV demonstrate the power of the super c-tau factory for light dark matter search.
