Inclusive π0 production by e+e- annihilation at 34.6 GeV center of mass energy
Zeitschrift für Physik C Particles and Fields 33:1 (1986) 13-22
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.Search for two-photon production of resonances decaying into K {Mathematical expression} and K {Mathematical expression}π

Abstract:
An analysis of the production of KS0KS0 and K±Ks0π∓ by two quasi-real photons is presented. The cross section for γγ→K0 {Mathematical expression}, which is given for the γγ invariant mass range from K {Mathematical expression} threshold to 2.5 GeV, is dominated by the f′(1525) resonance and an enhancement near the K {Mathematical expression} threshold. Upper limits on the product of the two-photon width times the branching ratio into K {Mathematical expression} pairs are given for Θ(1700), h(2030), and ξ(2220). For exclusive two-photon production of K±Ks0π∓ no significant signal was observed. Upper limits are given on the cross section of γγ→K+ {Mathematical expression}π- or K-K0π+ between 1.4 and 3.2 GeV and on the product of the γγ width times the branching ratio into the K {Mathematical expression}π final states for the ηc(2980) and the ι(1440), yielding Γ(γγ)→i(1440))·BR(i(1440)→K {Mathematical expression}π<2.2 keV at 95% C.L. © 1985 Springer-Verlag.SEARCH FOR 2-PHOTON PRODUCTION OF RESONANCES DECAYING INTO KKBAR AND KKBAR-PI
