description

In this paper we study the relationship between the ${D}_{s0}^{*}(2317{)}^{+}$ resonance and the decay of the ${B}_{c}$ meson into $J/\ensuremath{\psi}DK$. In this process, the ${B}_{c}$ meson decays first into $J/\ensuremath{\psi}$ and the quark pair $c\overline{s}$, and then the quark pair hadronizes into $DK$ or ${D}_{s}\ensuremath{\eta}$ components, which undergo final state interaction. This final state interaction, generating the ${D}_{s0}^{*}(2317{)}^{+}$ resonance, is described by the chiral unitary approach. With the parameters which allow us to match the pole position of the ${D}_{s0}^{*}(2317{)}^{+}$, we obtain the $DK$ invariant mass distribution of the decay ${B}_{c}\ensuremath{\rightarrow}J/\ensuremath{\psi}DK$, and also the rate for ${B}_{c}\ensuremath{\rightarrow}J/\ensuremath{\psi}{D}_{s0}^{*}(2317)$. The ratio of these two magnitudes is then predicted.
