We measure the branching fraction B(B-0 -> omega omega) = (1.2 +/- 0.3(-0.2)(+0.3)) x 10(-6), where the first uncertainty is statistical and the second is systematic, corresponding to a significance of 4.4 standard deviations. We also determine the upper limit B(B-0 -> omega phi) < 0.7 x 10(-6) at 90% confidence level. These measurements provide the first evidence for the decay B-0 -> omega omega, and an improvement of the upper limit for the decay B-0 -> omega phi. %R 10.1103/PhysRevD.89.051101 %U http://arxiv.org/abs/1312.0056 %U https://doi.org/10.1103/PhysRevD.89.051101 %P 051101-8pp
