Abstract
LHCb continues to expand its world-leading sample of charmed hadrons collected during LHC's Run 1 and Run 2. With this data set, LHCb is discovering many previously unobserved charmed states and making the most precise determinations of the properties of these states. This paper presents the recent LHCb results in charm spectroscopy, including the observation of five new excited $\Omega_c^0$ states, the study of excited $\Lambda_c^+$ states using the $\Lambda_b^0 \to D^0 p\pi^-$ decay, and the observation of the doubly charmed baryon $\Xi_{cc}^{++}$ in its decays to $\Lambda_c^+ K^-\pi^+\pi^+$ and $\Xi_c^+\pi^+$.
