Tests of QED at 29 GeV center-of-mass energy

Abstract: For models in which the constituents interact with vector couplings of strength g /4+-1, the energy scale A~for the contact interaction is measured to be greater than 1419. 0 GeV at the 95%%uo confidence level. %'e set limits on the production of supersymmetric scalar electrons through s-channel single-photon annihilation and t-channel inelastic scattering. Using events with two noncollinear electrons and no other charged or observed neutral particles in the final state, we see one event which is consistent wi… Show more

“…What, then, is the nature of the charge circulation? High energy scattering experiments limit the size of the electron to less that 10 −16 cm, [4] which rules out models of the electron as an extended body. After a lengthy analysis of the Dirac equation Bohm and Hiley conclude [5]: "the electron must still be regarded as a simple point particle whose only intrinsic property is its position."…”

“…Bender et al 8 =6.0  10 23 m This is well below the upper limit of the electron's size found in such high-energy scattering experiments. When a model of the photon is incorporated into the charged photon model, the size of the charged photon a high energies is expected to be larger than the above result, but the photon size is still expected to decrease with increasing  .…”
