  "abstract": "Based on a sample of $(2712.4 \\pm 14.3) \\times 10^6$ $ψ(3686)$ events collected with the BESIII detector at the BEPCII collider, we report the first observation of the decays $ψ(3686)\\to\\bar{p} K^{+} Σ^{*}(1385)^{0}+c.c.$ and $ψ(3686)\\to\\bar{p} K^{*}(892)^{0} Σ^{+} + c.c.$. The corresponding branching fractions are determined to be $\\mathcal{B}(ψ(3686)\\to\\bar{p}K^+Σ^{*}(1385)^{0}+c.c.)=(3.94\\pm0.15_{\\text{stat.}}\\pm0.24_{\\text{syst.}})\\times10^{-5}$ and $\\mathcal{B}(ψ(3686)\\to\\bar{p}K^{*}(892)^{0}Σ^++c.c.)=(4.93\\pm0.14_{\\text{stat.}}\\pm0.30_{\\text{syst.}})\\times10^{-5}$. Furthermore, we search for the hidden-strange pentaquark candidates $N_{x}(1875)$ and $N_{x}(2100)$ in the invariant mass spectra of $K^{+} Σ^{*}(1385)^{0}$ and $K^{*}(892)^{0} Σ^{+}$, respectively. No significant signals are observed and the upper limits on the branching fractions at the 90% confidence level are $\\mathcal{B}(ψ(3686)\\to\\bar{p}N_{x}(1875)\\to\\bar{p}K^+Σ^{*}(1385)^{0})<1.58\\times10^{-6}$ and $\\mathcal{B}(ψ(3686)\\to\\bar{p}N_{x}(2100)\\to\\bar{p}K^{*}(892)^{0}Σ^+)<3.09\\times10^{-7}$.",
