Tests of quantum electrodynamics at PETRA
Results from three PETRA experiments on d/sup +/e/sup -/ to e/sup +/e /sup -/ and e/sup +/e/sup -/ to mu /sup +/ mu /sup -/ are presented. These are used to test for deviations of the photon propagator from 1 /q/sup 2/ or for nonpoint like behavior of one of the particles gamma , e or mu . Quantum E...

| Sumario: | Results from three PETRA experiments on d/sup +/e/sup -/ to e/sup +/e /sup -/ and e/sup +/e/sup -/ to mu /sup +/ mu /sup -/ are presented. These are used to test for deviations of the photon propagator from 1 /q/sup 2/ or for nonpoint like behavior of one of the particles gamma , e or mu . Quantum Electrodynamics is found to be valid down to distances of 4*10/sup -16/ cm. (2 refs). |
