Abstract
We report new measurements relative to charmed hadron spectroscopy and measurement of charm hadron properties by the LHCb collaboration. Two new Xic0 baryons are observed, and the lifetimes of the Lc+, Xic0 and Xic+ baryons are measured with greatly improved precision compared to the current world average. The doubly Cabibbo-suppressed decays of Xic+->p phi and Xic0->Lc+pi- are observed for the first time. The most precise measurement of Xicc++ mass and production ratio is performed. Finally, the Xicc+ baryon is searched for in the Lc+K-pi+ final state.
