Hint for axial-vector contact interactions in the data on $e^{+}e^{-} \to e^{+}e^{-}(\gamma)$ at centre-of-mass energies 192-208 GeV
For the first time the experiments ALEPH, DELPHI, L3 and OPAL have presented preliminary results for fermion-pair production in e+e- collisions on the full data set above the Z pole. A combined analysis of the Bhabha scattering measurements is performed to search for effects of contact interactions....
