Studies on $B$ hadron production, spectroscopy and decays at CMS
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 $\Delta\Gamma_s$ in the $B_s \rightarrow J/\psi \phi$ decays. With an assumption of zero mixing phase,...

| Sumario: | 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
$\Delta\Gamma_s$ in the $B_s \rightarrow J/\psi \phi$ decays. With an
assumption of zero mixing phase, reconstructed $B_s$ signal candidates
are used to measure the polarization amplitudes in an angular and
proper decay time analysis. |
