The production of nal states involving one or more energetic photons from e + e collisions at high energies is studied using data collected by the ALEPH detector at LEP. The data consist of two samples of 2:9 p b 1 each, recorded at centre-of-mass energies of 130 GeV and 136 GeV. The data are in agreement with the predictions of the Standard Model. From an analysis of two-photon nal states new limits are placed on the parameters of models involving e + e contact interactions and exciteddoi:10.1016/0370-2693(96)00930-6 fatcat:7tznybe5kra3rilqwebydanywm
