LHCb measurements on CPV in $B$ decays ($B\rightarrow 3h$, $\phi_s$, charmless $B$ decays)

Abstract

The latest results on the

$CP$ violation measurements in

$B$
decays are reported. The measurement of the weak phase

$\phi_s^{s\overline{s}}$
using the

$B^0_s \to \phi\phi$ decay mode is performed on a dataset
corresponding to an integrated luminosity of

$5\,fb^{-1}$ collected in
proton-proton collisions by the LHCb experiment. Results on the first ever
measurement of the

$CP$ -violating phase

$\phi_s^{d\overline{d}}$ using

$B_s^0 \to (K^+\pi^-)(K^-\pi^+)$ channel,
based on

$3\,fb^{-1}$ of data, are summarised.
