Description
We review several recent results of the CMS experiment in the field of B hadron productions, spectroscopy and decays. A measurement of the &Lambdab lifetime using the decay &Lambdab to J/&psi Lambda is presented. The dataset was recorded with the CMS detector using a trigger selecting unbiased J/&psi decaying to dimuons. We performed a flavour-untagged measurement of the width difference &delta&Gammas in the Bs -> J/&psi &phi decays. With an assumption of zero mixing phase, reconstructed Bs signal candidates are used to measure the polarization amplitudes in an angular and proper decay time analysis.
