Abstract

We present perspectives for searching for light dark matter production mediated by a leptophilic scalar {\phi} and a dark photon A' in in experiments at the Super c-tau Factory. Based on the analysis of the associative production of mediators and {\tau} -leptons at the energies of the future collider, the possibility of searching in the non-excluded 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 SCTF for light dark matter search.
