摘要:

在大统一理论(GUT)启发的$SO(5)\times U(1)\times SU(3)$规范-Higgs统一中,研究了在$e^-e^+$直线对撞机实验中极化$e^-$和$e^+$光束的费米子对产生.在轻子和夸克与Kaluza-Klein(KK)激发的中性矢量玻色子$Z'$的耦合过程中,会出现较大的宇称破缺,导致不同过程中的截面具有明显的偏振依赖性,并出现前后不对称、左右不对称和左右前后不对称.在未来的$e^-e^+$线性对撞机实验中,即使在能量为250 $\,$ GeV到1 $\,$ TeV的KK质量尺度上,这些效应也是可以检测到的。

英文摘要:

Fermion pair production at $e^-e^+$ linear collider experiments with polarized $e^-$ and $e^+$ beams is examined in the GUT inspired $SO(5)\times U(1)\times SU(3)$ gauge-Higgs unification. There arises large parity violation in the couplings of leptons and quarks to Kaluza-Klein (KK) excited neutral vector bosons $Z'$s, which leads to distinctive polarization dependence in cross sections, forward-backward asymmetries, left-right asymmetries, and left-right forward-backward asymmetries in various processes. Those effects are detectable even for the KK mass scale up to about 15 TeV at future $e^-e^+$ linear collider experiments with energies 250$\,$GeV to 1$\,$TeV.
