We predict the correlation functions relevant in femtoscopy studies for $S$-wave $D_{(s)}\phi$ pairs, with $D_{(s)}$ a pseudoscalar open charm meson and $\phi$ a Goldstone boson, describing their interactions with next-to-leading order unitarized heavy-meson chiral perturbation theory amplitudes.

In the $(S,I)=(0,1/2)$ sector, the effect of the two-state structure around $2300\,\text{MeV}$ can be clearly seen in the correlation functions of the $D\pi$, $D\eta$, $D_s \overline{K}$ channels. In the $(1,0)$ sector, a depletion of the correlation function near the $DK$ threshold can be seen, produced by the $D^\ast_{s0}(2317)^{\pm}$ state lying below the $DK$ threshold.

These correlation functions could be experimentally measured, and will shed light into the hadron spectrum and, in particular, into the nature of these states.
