Özet

Analyzing (448.1 +/- 2.9) x 10(6) psi (3686) events collected with the BESIII detector at the BEPCII collider, the psi(3686) -> omega(KSKS0)-K-0 decay is observed for the first time. The branching fraction for this decay is determined to be B-psi(3686)->omega KS0KS0 = (7.04 +/- 0.39 +/- 0.36) x 10(-5), where the first uncertainty is statistical and the second is systematic.
