Results from PLUTO
Description
Recent results obtained with the PLUTO detector at the e+e- storage ring PETRA are reviewed. The validity of QED has been successfully tested in five independent reactions at spacelike momentum transfers up to -850 GeV2 and timelike momentum transfers up to 1000 GeV2. We are performing a detailed study of hadron production through 2 γ interactions. In particular we have measured the total hadronic γγ cross section and have determined the radiative width of the f0 meson to be GAMMA (f → γγ) = (2.3 +- 0.5 +- 0.35) keV. The first indication for the production of large P(t) jets in 2γ interactions is presented. We find no evidence for a tt threshold in the rate of inclusive muons. Finally we give a lower limit (95% c.1.) of 13 GeV on the mass of a spin 0 electron expected from supersymmetry
