Forward-backward asymmetry in e+e- -> nu nubar Z from anomalous CP-odd WWZ couplings
Saurabh D. Rindani, J. P. Singh
Abstract
Anomalous CP-odd W+W-Z couplings can give rise to a forward-backward asymmetry in the Z angular distribution in the e+e- centre-of-mass frame in the process e+e- -> nu nubar Z. Of the three CP-odd couplings possible, only the imaginary part of one of the couplings, f4Z, which is C odd and P even, contributes to the forward-backward asymmetry. It is found that a limit of the order of 0.1 can be placed on this coupling at a Next Linear Collider with centre-of-mass energy of 500 GeV and integrated luminosity of 50 fb-1.
