Description
B mesons provides an ideal laboratory for measurements of CP
violation and searches for CPV beyond the Standard Model. Recent
measurements of the mixing phases of the $B_s$ and $B_d$ mesons,
$\phi_s$ and
$\sin{2 \beta}$, using decays to $J\Psi$X final states are presented.
In view of
future improved measurements, a good understanding of pollution from
sub-leading penguin topologies in these decays is needed. Those can be
probed using suppressed decays like $B_s \to J/\Psi K_S$ and
$B_s \to J/\Psi K^*$. Recent results on these decay modes are
presented.
