$e^{+}e^{-}$ physics below $j/\psi$ resonance

Some recent results of e/sup +/e/sup -/ physics in the 1 to 2 GeV region are reviewed. They begin with studies of electromagnetic final states in wide angle bremsstrahlung and in photon-photon collisions. Next, the measurements of the hadronic production ratio R are presented, together with the new...

Sumario:Some recent results of e/sup +/e/sup -/ physics in the 1 to 2 GeV region are reviewed. They begin with studies of electromagnetic final states in wide angle bremsstrahlung and in photon-photon collisions. Next, the measurements of the hadronic production ratio R are presented, together with the new determination of the inclusive K degrees ratio. Then the exclusive multipion channels and the status of claimed vector meson recurrences is reviewed, as well as new results on electromagnetic form factors in the time-like region. (28 refs).
