Study of Extra Space Dimensions in Vector Boson Pair Production at LEP
Salvatore Mele, Eusebio Sanchez
TL;DR
This paper investigates the possibility of extra spatial dimensions affecting vector boson pair production at LEP, finding no deviations from the Standard Model and setting limits around 1 TeV on the models' scale.
Contribution
It provides experimental constraints on theories with extra dimensions by analyzing vector boson pair production at LEP energies.
Findings
No deviations from Standard Model observed
Limits of about 1 TeV set on extra dimension models
Experimental results constrain quantum gravity effects at LEP energies
Abstract
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.
