We present precise measurements of B hadron lifetimes performed by the CMS experiment at the LHC in proton-proton collisions at $\sqrt{s}=8\,$TeV. The first observation of $\Upsilon$ pair production and the search for X(5568) state are reported. The analyses are performed using a data sample corresponding to an integrated luminosity of about $20\,\mathrm{fb}^{-1}$.
