Feasibility study of $$D_s^+ \rightarrow \tau ^+ \nu _{\tau }$$ D s + → τ + ν τ decay and test of lepton flavor universality with leptonic $$D_s^+$$ D s + decays at STCF

Abstract We report a sensitive study of $$D_s^+ \rightarrow \tau ^+ \nu _{\tau }$$ D s + → τ + ν τ decay via $$\tau ^+ \rightarrow e^+ \nu _e \bar{\nu }_{\tau }$$ τ + → e + ν e ν ¯ τ with an integrated luminosity of 1 ab $$^{-1}$$ - 1 at the center-of-mass energy of 4.009 GeV at a future Super Tau C...
