摘要：
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 B-s(0) oscillation frequency Delta m(s). Then, flavor tagging is used to perform a measurement of the well known CKM angle sin2 beta in B-0 -> J/psi K-S(0), before we constrain phi(s) through an amplitude analysis of B-s(0) -> J/psi phi decays. These studies use about 35 pb(-1) of data taken in 2010. In addition, we present the measurement of B (B+ -> J/psi pi(+)) = B (B+ -> J/psi K+) and the first observation of B-s(0) -> J/psi f(2)' (1525).
