\ The CMS experiment at the LHC has reported new discoveries in flavor spectroscopy. In this talk, the observation of b (6100) ^- baryon, the decay ₀ᵇ J/ ^- K^+, the first observation of ^+ ^- ^+ ^- decay, and exotic resonances near the J/ J/ threshold are presented. All these results use the CMS data collected in proton-proton collisions at 13 TeV. \
