摘要：
We investigate the possibility of detecting the leptophilic gauge boson predicted by the model via the processes e(+ )e(-)-> l(+ )l(-)Z(x )(Z(x )-> l(+ )l(-)) and e(+ )e(-)-> l(+ )l(-)Z(x )(Z(x )-> v(l )v(l)) at the Circular Electron Positron Collider (CEPC) with a center of mass energy root s=240 GeV and luminosity . L = 5.6 ab(-1) We provide the expected sensitivities of the CEPC to the parameter space at the 1 sigma,2 sigma , 3 sigma, and 5 sigma levels.
