On the contribution of a heavy neutral particle to W-boson pair production in electron-positron annihilation
Description
The effect of a heavy neutral particle are obtained in the process e+e-->W+W- is studied. From the unitarity of the cross section limits on the mass and couplings of the N. Considering the contribution of this heavy particle to the anomalous magnetic moment of the electron a limit to the mixing angle between ordinary and excited (heavy) matter is inferred. (author)
