Study of extra space dimensions in vector boson pair production at LEP

Recent theoretical scenarios propose that quantum gravity effects may manifest at LEP energies by means of gravitons that couple to Standard Model particles and propagate into extra space dimensions. These predictions are checked against the most recent experimental results on photon, W and Z pair production. No deviations from the Standard Model expectations are found and limits of the order of 1 TeV on the scale of these models are set.

electron positron: annihilation
W: pair production
Z0: pair production
quantum gravity: effect
