First measurement of time-dependent CP violation in B[superscript 0][subscript s]→K[superscript +]K[superscript −] decays
Direct and mixing-induced CP-violating asymmetries in B[superscript 0][subscript s] → K[superscript +]K[superscript −] decays are measured for the first time using a data sample of pp collisions, corresponding to an integrated luminosity of 1.0 fb[superscript −1], collected with the LHCb detector a...

| description | Direct and mixing-induced CP-violating asymmetries in B[superscript 0][subscript s] → K[superscript +]K[superscript −] decays are measured for the first time using a data sample of pp collisions, corresponding to an
integrated luminosity of 1.0 fb[superscript −1], collected with the LHCb detector at a centre-of-mass energy of 7 TeV. The results are C[subscript KK] = 0.14 ± 0.11 ± 0.03 and S[subscript KK] = 0.30 ± 0.12 ± 0.04,
where the first uncertainties are statistical and the second systematic. The corresponding quantities are also determined for B[superscript 0] → π[superscript +]π[superscript −] decays to be C[subscript ππ] = −0.38±0.15±0.02 and S[subscript ππ] = −0.71 ± 0.13 ± 0.02, in good agreement with existing measurements. |
