Özet

Measurements of the branching fractions of B0 s→ K∗±K∓and B0 sK∗±π∓decays are performed using a data sample corresponding to 1.0 fb-1of proton-proton collision data collected with the LHCb detector at a centre-of-mass energy of 7 TeV, where the K∗±mesons are reconstructed in the K0 sπ±final state. The first observation of the B0 s→ K∗±K∓decay and the first evidence for the B0 s→ K∗-π+decay are reported with branching fractions (Equation presented), where the first uncertainties are statistical and the second are systematic. In addition, an upper limit of B(B0→ K∗±K∓) < 0.4 (0.5) × 10-6is set at 90% (95%) confidence level.
