A preliminary study of up three-prong annihilations into the channels K- K+ pi(+) and pi(-)pi(+)pi(+)pi(0) is presented for similar to 100-297 MeV/c ($) over bar n momenta. The extracted phi pi(+)/omega pi(+) production ratio shows that also in this channel, never measured before using an ($) over bar n beam, the OZI rule is strongly violated.

Abstract
A preliminary study of up three-prong annihilations into the channels K- K+ pi(+) and pi(-)pi(+)pi(+)pi(0) is presented for similar to 100-297 MeV/c ($) over bar n momenta. The extracted phi pi(+)/omega pi(+) production ratio shows that also in this channel, never measured before using an ($) over bar n beam, the OZI rule is strongly violated.
