Mass behavior of hidden-charm open-strange pentaquarks inspired by the established <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:msub><mml:mi>P</mml:mi><mml:mi>c</mml:mi></mml:msub></mml:math> molecular states

Stimulated by the meson-baryon molecular interpretations of $P_c$ states ($P_c(4312)/P_c(4440)/P_c(4457)$), we systematically study interactions between an $S-$wave charm-strange baryon $\Xi_c^{(\prime,*)}$ and anti-charmed meson $\bar{D}^{(*)}$ in a coupled channel analysis. Effective potentials for $\Xi_c^{(\prime,*)}\bar{D}^{(*)}$ one-boson-exchange model can be related to those $\Sigma_c^{(*)}\bar{D}^{(*)}$ systems using $SU(3)$ flavor symmetry heavy quark symmetry. Our results predict several promising hidden-charm pentaquarks with strangeness $|S|=1$, which include $\Xi_c^{\prime}\bar{D}$ $I(J^P)=0,1(1/2^-)$, $\Xi_c^*\bar{D}$ $0,1(3/2^-)$, $\Xi_c^{\prime}\bar{D}^*$ $0(1/2^-)$ $\Xi_c^*\bar{D}^*$ $0(1/2^-,3/2^-,5/2^-)$.
