Using a data sample of e^+e^- collisions corresponding to an integrated luminosity of 7.93 \rm fb^{-1} collected with the BESIII detector at the center-of-mass energy 3.773~GeV, we perform the first amplitude analysis of the decay D^{+} \to K_{S}^{0} K_{S}^{0} \pi^{+}. The absolute branching fraction of D^{+} \to K_{S}^{0}K_{S}^{0} \pi^{+} is... Show more
