Global Analysis of Bhabha Scattering at LEP2 and Limits on Low Scale Gravity Models

A global analysis of the data on Bhabha scattering from the four LEP experiments ALEPH, DELPHI, L3 and OPAL is performed to search for effects of virtual graviton exchange in models with low scale gravity. No statistically significant deviations from the Standard Model expectations are observed and...

description A global analysis of the data on Bhabha scattering from the four LEP experiments ALEPH, DELPHI, L3 and OPAL is performed to search for effects of virtual graviton exchange in models with low scale gravity. No statistically significant deviations from the Standard Model expectations are observed and lower limits on the scale of models with large extra dimensions of $\Lambda_T = 1.077 TeV$ for $\lambda = -1$ and $\Lambda_T = 1.412 TeV$ for $\lambda = +1$ at 95% confidence level are derived.
