  "abstract": "A study of resonant structures in $B^0 \\to D^{*-}D^0K^+$ decays is presented. The analysis uses proton-proton collision data collected by the LHCb experiment at center-of-mass energies of $\\sqrt{s} = 7$, 8, and 13 TeV, corresponding to an integrated luminosity of 9 fb$^{-1}$. The analysis demonstrates that the existing known excited $D_s^+$ resonances in the $D^0K^+$ spectrum are insufficient to describe the data. The inclusion of the tetraquark state $T_{c\\bar{c}1}(4430)^-$ improves the description of the data with a statistical significance exceeding $5σ$. This corresponds to the first observation of the $T_{c\\bar{c}1}(4430)^- \\to D^{*-} D^0$ decay. The measured properties of the $T_{c\\bar{c}1}(4430)^-$ state are consistent with those previously measured in its decay to the $ψ(2S)π^-$ final state.",
