摘要:

我们在CLIC上研究了非极化和极化电子束作用下的$e^{-}γ\to ν_eτ\barν_τ$($γ$是康普顿背散射光子)和$e^{-}e^{+} \to e^{-}γ^* e^{+} \to ν_{e}τ\barν_τe^+$($γ^*$是Weizsacker-Williams光子)过程中τ轻子的反常电磁矩。我们已经获得了95 $\%$置信水平界限的异常磁和电偶极矩的各种值的积分亮度和质心能量。与LEP灵敏度相比,已经获得了异常磁和电偶极矩的改进约束。

英文摘要:

We have examined the anomalous electromagnetic moments of the tau lepton in the processes $e^{-}γ\to ν_eτ\barν_τ$ ($γ$ is the Compton backscattering photon) and $e^{-}e^{+} \to e^{-}γ^* e^{+} \to ν_{e}τ\barν_τe^+$ ($γ^*$ is the Weizsacker-Williams photon) with unpolarized and polarized electron beams at the CLIC. We have obtained 95$\%$ confidence level bounds on the anomalous magnetic and electric dipole moments for various values of the integrated luminosity and center-of-mass energy. Improved constraints of the anomalous magnetic and electric dipole moments have been obtained compared to the LEP sensitivity.
