Study of ${D}^{+}\to {K}_{S}^{0}{K}^{*}\left(892{\right)}^{+}$ in ${D}^{+}\to {K}_{S}^{0}{K}_{S}^{0}{\pi }^{+}$

Using a data sample of ${e}^{+}{e}^{-}$ collisions corresponding to an integrated luminosity of $7.93\text{}\text{}{\mathrm{fb}}^{-1}$ 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 measured to be $\left(2.97±0.0{9}_{\mathrm{stat}}±0.0{5}_{\mathrm{syst}}\right)×{10}^{-3}$. The dominant intermediate process is ${D}^{+}\to {K}_{S}^{0}{K}^{*}\left(892{\right)}^{+}$, whose branching fraction is determined to be $\left(8.72±0.2{8}_{\mathrm{stat}}±0.1{5}_{\mathrm{syst}}\right)×{10}^{-3}$, including all the ${K}^{*}\left(892{\right)}^{+}$ decays.
