  • Hadronic events in $e^+ e^-$ collisions

Ratios (w.r.t. $\pi^+/\pi^-$) of hadron multiplicities in hadronic $e^+ e^-$ events, taken from Review of Particle Properties 2008, table 40.1, page 355. Average hadron multiplicities per hadronic $e^+ e^-$ annihilation event at $\sqrt{s} \approx$ 10, 29--35, 91, and 130--200 GeV, normalised to the pion multiplicity. The numbers are averages from various experiments. Correlations of the systematic uncertainties were considered for the calculation of the averages.
