Study on the energy asymmetries and optimal observables of CP violation in e^+e^-→t t process

考察了e+e-→tt过程中CP破坏的能量反对称性和最佳测量量问题 ,表明相应CP破坏的能量反对称性和最佳测量量取决于弱电偶极矩形式因子的虚数部分 ,也说明初态e+e-束的极化对于解析Imdγ(s)和ImdZ(s)是必不可少的 。

This paper studies the energy asymmetries and optimal observables of CP violation in e +e -→t t process,finds that the corresponding CP violating energy asymmetries and optimal observables are determined the imaginary parts of the electric and weak dipole moment form factors,shows that the polarization of the initial lepton beam is essential to disentangle Im d γ(s) and Im d Z(s) ,and gives the numerical results in the walking extended technicolor model.
