Observation of the $T_{c\bar{c}1}(4430)^-$ state in $B^0\to D^{*-}D^0K^+$ decays

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 demonstrat
