Abstract
The {\bar p}p-annihilation reactions {\bar p}p-->eta eta eta and {\bar p}p--> eta K{\bar K} at rest are considered in the tree approximation in the framework of SU(3) chiral effective theory at leading order. The calculated branchings are compared with the data. The results for neutral (eta eta eta, K^0{\bar K^0}eta) and charged (K^+ K^- eta) channels are essentially different.
