Deenition of Variables and Limits for Studying the E + E ? ! Reaction
نویسندگان
چکیده
The reaction e + e ? ! is an ideal process to test QED in e + e ? collisions, since it does not receive tree level contribution from the exchange of weak bosons. It can thus be used to set limits on the energy scale of new interactions. In this note we review two technical aspects related to the study of the e + e ? ! reaction: the deenition of the scattering angle, which is aaected by the presence of radiative corrections , and the methods used to set limits on the energy scale of new interactions. We also show an application of these methods to the LEP 1 dataset.
