Beam-beam effects on the luminosity measurement at LEP and the number of light neutrino species
In e+e− collisions, electromagnetic effects caused by large charge density bunches modify the effective acceptance of the luminometer system of the experiments. These effects consequently bias the luminosity measurement from the rate of low-angle Bhabha interactions e+e−→e+e− . Surprisingly enough,...
