First observation of the decay B s 0→K *0K̄ *0
The first observation of the decay B s 0→K *0K̄ *0 is reported using 35 pb -1 of data collected by LHCb in proton-proton collisions at a centre-of-mass energy of 7 TeV. A total of 49.8±7.5 Bs0→(K +π -)(K -π +) events are observed within ±50 MeV/c 2 of the B s 0 mass and 746 MeV/c 2
