Latest results on exotic hadrons at LHCb

<!--HTML--><p>Exotic hadrons, which cannot be described as conventional mesons ($q\bar{q}$) or baryons ($qqq$), can provide new insights into the internal structure and dynamics of hadrons, thus improving our knowledge of the non-perturbative regime of QCD. Since 2003, various candidates for exotic states have been observed, to which the LHCb experiment has made major contributions. This seminar highlights the most recent results on exotic hadrons at LHCb, including precise measurements of mass and width of the $\chi_{c1}(3872)$ state based on the Breit-Wigner lineshape, a study of the $\chi_{c1}(3872)$ lineshape using a Flatté-inspired model, and an investigation of the di-charmonium system.</p>
