{\bar p}p-annihilation processes in the tree approximation of SU(3)
chiral effective theory    [PDF]

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.
