Abstract

The process e+e-→ π0 + anything has been measured at c.m. energies of 14 and 34 GeV for π0 energies between 0.5 and 4 GeV. The ratio of π0 to π± production for π momenta between 0.5 and 1.5 GeV/c is measured to be 2σ(π0)/ [σ(π+) + σ(π-)] = 1.3 ± 0.4 (1.2 ± 0.4) at 14 (34) GeV. The scaled cross section (s/μ)dσ/dx when compared with lower energy (4.9-7.4 GeV) π0 data indicates a substantial scaling violation. © 1982.
