  "abstract": "We present the first amplitude analysis and branching fraction measurement of $D^{+} \\rightarrow K_{S}^{0}K_{L}^{0}π^{+}$ decay. The analysis uses a dataset corresponding to an integrated luminosity of 20.3~$\\rm fb^{-1}$, which was recorded at a center-of-mass energy 3.773~GeV by the BESIII detector. The measured branching fraction is $\\mathcal{B}(D^{+} \\rightarrow K_{S}^{0}K_{L}^{0}π^{+})=(5.780\\pm0.085\\pm 0.052)\\times10^{-3}$, where the first uncertainty is statistical and the second is systematic. Using the known value of ${\\cal B}(D^+ \\to ϕπ^+,\\,ϕ\\to K^+K^-)$, we determine the relative branching fraction between $ϕ\\to K_{S}^0K_{L}^0$ and $ϕ\\to K^+K^-$ to be $\\mathcal{B}(D^{+} \\to ϕπ^{+}, ϕ\\to K_{S}^0K_{L}^0)/\\mathcal{B}(D^{+} \\to ϕπ^{+}, ϕ\\to K^+K^-)= 0.628\\pm0.022\\pm 0.015\\pm0.017$, where the third uncertainty is related to $\\mathcal{B}(D^{+} \\to ϕπ^{+}, ϕ\\to K^+K^-)$. This result is significantly lower than the previous world average and is consistent with the isospin expectation for the $ϕ$ meson's coupling to charged and neutral kaon pairs.",
