Open charm Spectroscopy and exotic states at LHCb

Abstract

We present a summary of new experimental results on the status of the charm spectroscopy using inclusive approaches and Dalitz plot analyses of $B$ and $B_s$ decays. We also report on a new determination of the $X(3872)$ quantum numbers.Comment: To be published in the proceedings of CHARM-2015, Detroit, MI, 18-22 May 201
