description We present studies from the LHCb experiment leading to the measurement of the weak phase {\phi}s. At first, flavor tagging is established by measuring the B0s oscillation frequency \Deltams. Then, flavor tagging is used to perform a measurement of the well known CKM angle sin 2{\beta} in B0 \rightarrow J/{\psi} KS0, before we constrain {\phi}s through an amplitude analysis of B0s \rightarrow J/{\psi} {\phi} decays. These studies use about 35 inverse pb of data taken in 2010. In addition, we present the measurement of B(B+\rightarrowJ/{\psi}{\pi}+)/B(B+\rightarrowJ/{\psi}K+) and the first observation of B0s \rightarrowJ/{\psi}f2'(1525).

At first, flavor tagging is established by measuring the Bs0 oscillation frequency Δms. Then, flavor tagging is used to perform a measurement of the well known CKM angle sin 2β in B0 → J/ψK0s, before we constrain φs through an amplitude analysis of Bs0 → J/ψ φ decays. These studies use about 35 pb−1 of data taken in 2010. In addition, we present the measurement of B(B+ → J/ψ π+)/B(B+ → J/ψ K+) and the first observation of Bs0 → J/ψ ƒ′2 (1525).We present studies from the LHCb experiment leading to the measurement of the weak phase {\phi}s.
