A MEASUREMENT OF SIGMA-TOT (E+E--]HADRONS) FOR CM ENERGIES BETWEEN 12.0 AND 36.7-GEV

A MEASUREMENT OF SIGMA-TOT (E+E--]HADRONS) FOR CM ENERGIES BETWEEN 12.0 AND 36.7-GEV

The ration R = σ(e+e- → hadrons)σμμ was measured between 12.0 and 36.7 GeV c.m. energy W with a precision of typically ± 5.2%. R is found to be constant with an average R = 4.01 ± 0.03 (stat) ± (syst.) for W ≥ 14 GeV. Quarks are found to be point-like, the mass parameter describing a possible quark...
