$CP$ violation in heavy-flavour hadrons / Cowan, Greig A. (Edinburgh U.) /LHCb Collaboration
Measurements of $CP$-violating observables in $B$ meson decays can be used to determine the angles of the Unitarity Triangle and hence probe for manifestations of New Physics beyond the Cabibbo-Kobayashi-Maskawa Standard Model paradigm. Of particular interest are precise measurements of the angles $\gamma$ and $\beta$. [...]

Measurements of $\phi_s$ at the LHCb experiment / Cowan, Greig A. (Edinburgh U.) /LHCb Collaboration
These proceedings present the current status of measurements of the CP-violating phase $phi_s$ by the LHCb collaboration, reviewing the measurements in channels such as $B_s^0\to J/\psi\phi$, $B_s^0\to J/\psi \pi^+\pi^-$ and $B_s^0 \to \psi(2S)\phi$. The observation of the $B_s^0\to\eta_c\phi$ decay mode is presented for the first time, which can be used to measure $\phi_s$ with larger data samples that will be collected over the coming years by the LHCb experiment. [...]

Measurements of CP violation in B mixing through $B \to J/\psi X$ decays at LHCb / Cowan, Greig A. (Edinburgh U.)
B mesons provide an ideal laboratory for measurements of CP violation and searches for CP violation beyond the Standard Model. Recent measurements of the mixing phases of the $B_s^0$ and $B^0$ mesons, $\phi_s$ and $\sin2\beta$, using decays to $J/\psi X$ final states are presented. [...]

Determination of the CP-violating phase in $B_s^0 \to J/\psi\phi$ decays at LHCb / Cowan, Greig A (Edinburgh U.)
Flavour-tagged, time-dependent, angular analysis of the decay $B^0_s \to J/\psi \phi$ allows the determination of a CP-violating phase which in the Standard Model is denoted $-2\beta_s$, and is predicted to be very small. [...]
