Processes of electron-positron annihilation into a pair of fermions were considered. Forward-backward and left-right asymmetries were studied, taking into account polarization of initial and final particles. Complete 1-loop electroweak radiative corrections were included. A wide energy range including the $Z$ boson peak and higher energies relevant for future $e^+e^-$ colliders was covered. Sensitivity of observable asymmetries to the electroweak mixing angle and fermion weak coupling was discussed.

电子-正电子湮灭过程中的不对称性

考虑了正负电子湮灭成一对费米子的过程。研究了前后和左右不对称，同时考虑了初始和最终粒子的极化。包括完整的 1 环电弱辐射校正。涵盖了广泛的能量范围，包括 $Z$ 玻色子峰和与未来 $e^+e^-$ 对撞机相关的更高能量。讨论了可观察到的不对称性对电弱混合角和费米子弱耦合的敏感性。
