 B Physics and Quarkonia at CMS / Wulz, Claudia (Vienna, OAW) /CMS Collaboration Selected recent results on B physics and quarkonia are presented. These include a determination of the CP-violating phase $\phi_s$ and the decay width difference $\Delta\Gamma_s$ of the light and heavy B$_s$ states with B$_s \rightarrow$ J$/\psi~\Phi$(1020), prompt double-differential production cross sections of J$/\psi$ and $\psi$(2S), and polarization measurements for J/$\psi$, $\psi$(2S), $\Upsilon$(1S), $\Upsilon$(2S), and $\Upsilon$(3S).

 Measurement of CP Violation in $\mathrm{B}^{0}_{\mathrm{s}} \! \to \mathrm{J} \! / \! \psi\,\phi$ decays with the CMS detector / Pazzini, Jacopo (INFN, Padua ; Padua U.) /CMS Collaboration The CP-violating weak phase $\phi_\mathrm{s}$ and the decay width difference $\Delta\Gamma_{\mathrm{s}}$ of $\mathrm{B}^{0}_{\mathrm{s}}$ mesons are measured by the CMS experiment at the LHC using a data sample of $\mathrm{B}^{0}_{\mathrm{s}} \! \to \mathrm{J} \! / \! \psi\,\phi$ decays. The analysed dataset corresponds to an integrated luminosity of about $20~\mathrm{fb}^{-1}$ collected in $pp$ collisions at a centre-of-mass energy $\sqrt{s} = 8~\mathrm{TeV}$.

 Design of CMS Beam Halo Monitor system / Orfanelli, Stella (CERN) /CMS Collaboration A fast and directional monitoring system for the CMS experiment is designed to provide an online, bunch-by-bunch measurement of beam background induced by beam halo interactions, separately for each beam. The background detection is based on Cherenkov radiation produced in synthetic fused silica read out by a fast, UV sensitive photomultiplier tube. [...] CMS-CR-2014-133.- Geneva : CERN, 2014 - 7 p.
