| contents | Motivated by the observed $P_{ψs}^Λ(4459)/P_{ψs}^Λ(4338)$ and $T_{cc}(3875)^+$ states as the $Ξ_c \bar D^{*}/Ξ_c \bar D$ and $DD^{*}$ molecular candidates, respectively, in this work we investigate the $Ξ_c^{(\prime,*)} D^{(*)}$ molecular systems. We obtain the mass spectra and the corresponding spatial wave functions of the $Ξ_c^{(\prime,*)} D^{(*)}$-type double-charm molecular pentaquark candidates with single strangeness, where we utilise the one-boson-exchange model and take into account both the $S$-$D$ wave mixing effect and the coupled channel effect. Our results show that the most promising candidates of the double-charm molecular pentaquarks with single strangeness include the $Ξ_c D$ state with $I(J^P)=0(1/2^-)$, the $Ξ_c^{\prime} D$ state with $I(J^P)=0(1/2^-)$, the $Ξ_c D^{*}$ states with $I(J^P)=0(1/2^-,3/2^-)$, the $Ξ_c^{*} D$ state with $I(J^P)=0(3/2^-)$, the $Ξ_c^{\prime} D^{*}$ states with $I(J^P)=0(1/2^-,3/2^-)$, and the $Ξ_c^{*} D^{*}$ states with $I(J^P)=0(1/2^-,3/2^-,5/2^-)$. To gain further insight into the inner structures and the properties of the isoscalar $Ξ_c^{(\prime,*)} D^{(*)}$ molecular candidates, we utilize the constituent quark model to analyze their M1 radiative decay behaviors and magnetic moments based on the obtained mass spectra and spatial wave functions, which can offer the significant information to determine their spin-parity quantum numbers and configurations in the forthcoming experiments. We suggest that our experimental colleagues search for the predicted $Ξ_c^{(\prime,*)} D^{(*)}$ molecular states. |
