The $ φπ^{+} $/$ ωπ^{+} $ ratio from%$\bar np%$ annihilationsannihilations

Summary A preliminary study of%$\bar np%$ three-prong annihilations into the channels $ K^{−} $ $ K^{+} $ $ π^{+} $ and $ π^{−} $ $ π^{+} $ $ π^{+} $ $ π^{0} $ is presented for ∼ 100–297 MeV/c%$\bar n%$ momenta. The extracted $ φπ^{+} $/$ ωπ^{+} $ production ratio shows that also in this channel, ne...

Summary A preliminary study of%$\bar np%$ three-prong annihilations into the channels $ K^{−} $ $ K^{+} $ $ π^{+} $ and $ π^{−} $ $ π^{+} $ $ π^{+} $ $ π^{0} $ is presented for ∼ 100–297 MeV/c%$\bar n%$ momenta. The extracted $ φπ^{+} $/$ ωπ^{+} $ production ratio shows that also in this channel, never measured before using an%$\bar np%$ beam, the OZI rule is strongly violated. Ausführliche Beschreibung
