For the B 0 B0 dimuon decay, an upper limit on the branching fraction is set at B(B 0 ?µ + µ - )<4.2×10 -10 B(B0?µ+µ-)<4.2×10-10 at 95 % confidence level. For B 0 s Bs0, the branching fraction B(B 0 s ?µ + µ - )=(0.9 +1.1 -0.8 )×10 -9 B(Bs0?µ+µ-)=(0.9-0.8+1.1)×10-9 is measured. The results are consistent with the Standard Model expectation with a p value of 4.8 %, corresponding to 2.0 standard deviations.
