【 摘 要 】

We review several recent results of the CMS experiment in the field of B hadron productions, spectroscopy and decays. We performed a flavour-untagged measurement of the width difference ΔΓs in the Bs → J/ψφ decays. With an assumption of zero mixing phase, reconstructed Bssignal candidates are used to measure the polarization amplitudes in an angular and proper decay time analysis.
