Abstract:

Vector meson production is studied in the reaction γγ→K+K-π+π-. A clear Φ(1020) signal is seen in the K+K- mass distribution and a K*0 (890) signal is visible in the K±π∓ one. Both do not seem to be strongly correlated with quasi two body final states. Cross sections for the processes γγ→K+K-π+π-, γγ→Φπ+π-, γγ→K+0K±π∓ and upper limits for the production of Φp, ΦΦ and K*0 {Mathematical expression} are given as function of the invariant γγ mass. © 1986 Springer-Verlag.

Abstract:

The cross section for the process e+e-→π0+ anything has been measured at an average center of mass energy of 34.6 GeV for π0 energies between 0.7 and 17 GeV. The angular distribution for π0 energies larger than 2 GeV is of the form dσ/dΩ∼1+Acos2θ, with A=1.2±0.5. The ratio of π0 to π± production in the measured energy range is 2σ(π0)/(σ(π+)+σ(π-))=1.13±0.18 The form of the differential cross sections agrees within the errors. The mean π0 multiplicity is 5.8±0.9. © 1986 Springer-Verlag.
