Measurement of the CP-violating weak phase $\mathrm{ \phi_s }$ and the decay width difference $ \Delta \Gamma_{ \mathrm{s} }$ using the $ \mathrm{B^0_s} \to \mathrm{J} / \psi \phi(1020) $ decay channel in pp collisions at $\sqrt{s} =$ 8 TeV
The CP-violating weak phase $ \mathrm{ \phi_s } $ of the $ \mathrm{ B^0_s } $ meson and the decay width difference $\Delta \Gamma_{ \mathrm{s} }$ of the $ \mathrm{ B^0_s } $ light and heavy mass eigenstates are measured with the CMS detector at the LHC using a data sample of $ \mathrm{ B^0_s } \to \mathrm{J} / \psi \phi(1020) \to \mu^+ \mu^- \mathrm{ K^{+} K^{-} } $ decays.

A precise measurement of the $B^0$ meson oscillation frequency / Vecchi, Stefania (Universita di Ferrara (IT)) /LHCb Collaboration
The oscillation frequency of $B^0$ mesons is measured using semileptonic decays with a charged $D$ or $D^*$ meson in the final state, on a data sample collected by the LHCb detector corresponding to an integrated luminosity of 3 fb$^{-1}$ of $pp$ collisions. A combination of the two decay modes gives $\Delta m_d = (503.6 \pm 2.0 \pm 1.3)$ ns$^{-1}$ , where the first uncertainty is statistical and the second systematic [...]

Interplay among transversity induced asymmetries in hadron leptoproduction / Adolph, C. ; Akhunzyanov, R. ; Alexeev, M.G. ; Alexeev, G.D. ; Amoroso, A. ; Andrieux, V. ; Anosov, V. ; Augustyniak, W. ; Austregesilo, A. ; Azevedo, C. et al. /COMPASS
In the fragmentation of a transversely polarized quark several left-right asymmetries are possible for the hadrons in the jet. When only one unpolarized hadron is selected, it exhibits an azimuthal modulation known as Collins effect. [...]

Measurement of the underlying event activity using charged-particle jets in proton-proton collisions at $\sqrt{s}=$ 2.76 TeV
A measurement of the underlying event (UE) activity in proton-proton collisions is performed using events with charged-particle jets produced in the central pseudorapidity region ($ |{\eta^{\text{jet}}} |$ less than 2) and with transverse momentum $p_{\mathrm{T}}^\text{jet}$ between 1 and 100 GeV.

Search for pair-produced vector-like B quarks in proton-proton collisions at $\sqrt{s} =$ 8 TeV
A search for the production of a heavy B quark, having electric charge ${-}1/3$ and vector couplings to W, Z, and H bosons, is carried out using proton-proton collision data recorded at the CERN LHC by the CMS experiment, corresponding to an integrated luminosity of 19.7 fb$^{-1}$. [...]

Study of the $B_c^+ \to J/\psi D_s^+$ and $B_c^+ \to J/\psi D_s^{*+}$ decays with the ATLAS detector
The decays $B_c^+ \to J/\psi D_s^+$ and $B_c^+ \to J/\psi D_s^{*+}$ are studied with the ATLAS detector at the LHC using a dataset corresponding to integrated luminosities of 4.9 fb$^{-1}$ and 20.6 fb$^{-1}$ of $pp$ collisions collected at centre-of-mass energies $\sqrt{s} = 7$ TeV and 8 TeV, respectively.
