Abstract: | New results on the multihadron production by electron and positron beams colliding with a total energy of up to 3 GeV are reported. Disregarding possible kaon final states, the ratio σmh/σμμ of the total multihadron cross-section to the point-like cross section for process e+e?→μ+μ? has an average value of 1.58 ± 0.25 in the energy interval 2.6–3.0 GeV. The average charged multiplicity over this energy range is 〈nc〉 = 2.9 ± 0.3. |
