通过e+e-> nu anti-nu gamma过程探讨Z_Z_gamma和Z_G_G_G_G_G_G耦合
Probing the ZZgamma and Zgammagamma Couplings Through the Process e+e- --> nu anti-nu gamma
摘要:
本文研究了在高能直线对撞机上用$e^+e^-\to ν\barνγ$过程检验反常三重规范耦合$ZZγ$和$Zγγ$的灵敏度。对于积分亮度为500 $fb^{-1}$和质心能量在0.5和1.5 $TeV$之间的情况,我们发现这个过程可以提供$10^{-4}$级的三重中性规范玻色子耦合的测试,比标准模型预测的低一个数量级。
英文摘要:
We study the sensitivity for testing the anomalous triple gauge couplings $ZZγ$ and $Zγγ$ via the process $e^+e^-\to ν\barνγ$ at high energy linear colliders. For integrated luminosities of 500 $fb^{-1}$ and center of mass energies between 0.5 and 1.5 $TeV$, we find that this process can provide tests of the triple neutral gauge boson couplings of order $10^{-4}$, one order of magnitude lower than the standard model prediction.
