The Applicability of Zweig's Rule to anti-p p Annihilations at 3.6-GeV/c

Donald, R.A. ; Edwards, D.N. ; Houlden, M. ; et al.
Phys.Lett.B 61 (1976) 210-212, 1976.
Inspire Record 113109 DOI 10.17182/hepdata.27692

The final states øππ and øKK̄ arising from p̄p annihilations at 3.6 GeV/ c have been studied. The results are in agreement with Zweig's rule contrary to what is observed in high energy pp collisions.

anti-p + p ---> K+ + K- + pi+ + pi- reaction in the momentum range 400-MeV/c to 670-MeV/c

Fukushisa, R. ; Kishida, T. ; Komatsubara, T.K. ; et al.

The cross sections for the reaction p¯+p→K++K−+π++π− were measured at six momenta from 400 to 670 MeV/c. Various effective mass distributions indicate that about 37% of the reaction involves K*0 or K¯*0, 16% proceeds via the intermediate state K*0+K¯*0, about 21% involves ρ, 5% proceeds via the ϕ+ρ state, and the rest follows phase space.

anti-Proton-Proton Annihilations Between 1.5-GeV/c and 2.0-GeV/c: Final States with at Least One K0(L) Meson

Inspire Record 3307 DOI 10.17182/hepdata.37675

Antiproton-proton annihilations into final states containing one or two K10-mesons are studied on the basis of 450 000 pictures from the CERN 2 m HBC. The experiment covers the domain of antiproton incident momentum from 1.50 to 2.04 GeV/c. The resonance production rates are computed for the most abundant channels. The K10K10 threshold effect is explained through the inelastic channel π+π− → K10K10. The decay modes D, E → δ±(975)π∓, δ±(975) → K10K± are pointed out. The strange mesons C and C′ are observed in these annihilations and come mainly from the two-body channels \(p\bar p\) → (C, C′)K and\(p\bar p\) → (C, C′)K*.

Phi and omega Meson Production in anti-p p Annihilations at 0.7-GeV/c-0.76-GeV/c and the OZI Rule

The production of the φ and ω mesons has been studied in the reactions p p → φ(ω)π + π − and p p → φ(ω) ϱ 0 at 0.70–0.76 GeV /c . The c.m. angular distribution of the φ meson in the reaction p p → φπ + π − is found to be consistent with isotropy. The corresponding distribution for ω is not. the ratio σ( p p → φπ + π − ) σ( p p → ωπ + π − ) is (10 ± 2.4) · 10 −3 , which leads to a value of (19 ± 5) · 10 −3 when corrected for the phase-space factor. Implications of this result for the OZI rule are discussed.
