Description
The discovery of new hadronic states, particularly those considered exotic (tetraquarks, hadronic molecules, etc.), is fundamental to reduce the lack of knowledge on the QCD bound states rules. At the experimental level, in some cases, the measured nature of the new states and their properties do not match the theory predictions, making their nature unclear. This is the case of the $D_{s0}*(2317)^+$ and $D_{s1}(2460)^+$ states, expected to be excited states on the [cs] spectrum but with measured properties consistent to be [cusu] tetraquark states, or $D^{(*)}K$ molecules. The existing measurements are not enough to provide a clear insight about the $D_{sJ}(M)^+$ properties hence new observables are required to discern its possible exotic nature. In this talk, recent results published by LHCb about the $D_{sJ}(M)^+$ nature as well as the ongoing analysis on these hadrons will be shown.
