A preliminary study of n¯p three-prong annihilations into the channels K− K+ π+ and π− π+ π+ π0 is presented for ∼ 100–297 MeV/c n¯ momenta. The extracted φπ+/ωπ+ production ratio shows that also in this channel, never measured before using an n¯p beam, the OZI rule is strongly violated.

Abstract
A preliminary study of n¯p three-prong annihilations into the channels K− K+ π+ and π− π+ π+ π0 is presented for ∼ 100–297 MeV/c n¯ momenta. The extracted φπ+/ωπ+ production ratio shows that also in this channel, never measured before using an n¯p beam, the OZI rule is strongly violated.File in questo prodotto:
