### Speaker

The CMS and TOTEM experiments have jointly collected data from pp collisions at $\sqrt{s}$ = 13 TeV in a special LHC run at the end of 2015. We discuss a preliminary analysis concerning the possibility of observation of diffractive open charm mesons in the channels $D^{+*}\rightarrow D^{0} + \pi^{+} \rightarrow K^{+} + \pi^{-} + \pi^{+}$ (c.c) and $D^{0} \rightarrow K^{+} + \pi^{-}$ (c.c) taking advantage of TOTEM’s proton tagging capability. The analysis is based on the reconstruction of the $D^{0}$ and $D^{+}$ in the central detector (CMS), combined with the proton reconstructed by the forward detector (TOTEM), in order to select central diffractive events. The results are compared with a Monte Carlo simulation that reproduces the conditions the data were collected.
