Many exotic resonances have been recently observed at the LHC and other experiments. In this report,
CMS studies of exotic multiquark states are reported using the data collected in pp collisions at sqrt(S)
= 13 TeV.
Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating very compact bibliographies which can be beneficial to authors and readers, and in "proceeding" format which is more detailed and complete.
