Aaij R, Abellan Beteta C, Adeva B, et al., 2012, Measurement of the CP violating phase phi(s) in (B)over-bar(s)(0) -> J/psi f(0)(980), Physics Letters B, Vol: 707, Pages: 497-505, ISSN: 0370-2693
Measurement of mixing-induced CP violation in B0s decays is of prime importance in probing new physics.So far only the channel B0s → J/ψφ has been used. Here we report on a measurement using an LHCbdata sample of 0.41 fb−1, in the CP odd eigenstate J/ψ f0(980), where f0(980) → π+π−. A timedependentfit of the data with the B0s lifetime and the difference in widths of the heavy and lighteigenstates constrained to the values obtained from B0s → J/ψφ yields a value of the CP violating phaseof −0.44 ± 0.44 ± 0.02 rad, consistent with the Standard Model expectation.

A measurement of the effective B0s → K + K − lifetime is presented using approximately 37 pb−1 of datacollected by LHCb during 2010. This quantity can be used to put constraints on contributions fromprocesses beyond the Standard Model in the B0s meson system and is determined by two complementaryapproaches asτK K = 1.440 ± 0.096 (stat) ± 0.008 (syst) ± 0.003 (model) ps.

The first observation of the decay B0s → D0K∗0 using pp data collected by the LHCb detector at a centreof-massenergy of 7 TeV, corresponding to an integrated luminosity of 36 pb−1, is reported. A signalof 34.4 ± 6.8 events is obtained and the absence of signal is rejected with a statistical significance ofmore than nine standard deviations. The B0s → D0K∗0 branching fraction is measured relative to that ofB0 → D0ρ0: B(B0s →D0 K∗0)B(B0→D0ρ0) = 1.48±0.34±0.15±0.12, where the first uncertainty is statistical, the secondsystematic and the third is due to the uncertainty on the ratio of the B0 and B0s hadronisation fractions
