ϕ-Meson Production in the Reactionsπ±N→K−K+Nat 6 GeV/c

..phiN shows a flat t distribution (slope=1.7 +- 0.2 GeV/sup -2/) and a cross section suppressed by 0.0032 +- 0.0004 relative to ..pi../sup -/p..--> omega..n. Natural-parity-exchange ..omega.. and phi production have similar t dependences, while ..omega.. and phi production by unnatural-parity exchange differ markedly. Interference between the phi and the underlying K-barK S wave indicates substantial nucleon-spin incoherence between the amplitudes for phi and S-wave production. -->

Popis: A sample of 1200 phi mesons produced in the Zweig-rule-forbidden reactions ..pi../sup plus-or-minus/N..-->..phiN shows a flat t distribution (slope=1.7 +- 0.2 GeV/sup -2/) and a cross section suppressed by 0.0032 +- 0.0004 relative to ..pi../sup -/p..--> omega..n. Natural-parity-exchange ..omega.. and phi production have similar t dependences, while ..omega.. and phi production by unnatural-parity exchange differ markedly. Interference between the phi and the underlying K-barK S wave indicates substantial nucleon-spin incoherence between the amplitudes for phi and S-wave production.
