Measurements of time-dependent b-hadron properties in LHCb

This paper presents three key time-dependent measurements of $b$-hadron properties using LHCb Run 2 data: an improved determination of the CKM phase $\phi_s$ via $B_s^0\to J/\psi\pi^+\pi^-$, the first observation of CP-violation in $B^0\to J/\psi\rho^0(770)$ decays, and the first measurement of time-dependent CP-violation in the $b\to s l^+ l^-$ process $B_s^0 \to K_S \mu^+ \mu^-$.
