本文研究了Kaluza-Klein激发的中性矢量玻色子（Z′玻色子）在规范-希格斯统一中对e+ e−→ q q，ε + ε −截面的影响，特别是在未来的极化束e+ e−对撞机实验中的影响。预测了σ（μ+ μ−）、轻子前后不对称性、R B（μ）σ（B B）/σ（μ+ μ−）和左右不对称性的能量和偏振依赖性与标准模型的显著偏差。
Abstract Effects of Kaluza–Klein excited neutral vector bosons (Z′ bosons) in the gauge-Higgs unification on e+ e−→ q¯ q, ℓ+ ℓ− cross sections are studied, particularly in future e+ e− collider experiments with polarized beams. Significant deviations in the energy and polarization dependence in σ (μ+ μ−), the lepton forward–backward asymmetry, R b (μ)≡ σ (b¯ b)/σ (μ+ μ−) and the left–right asymmetry from the standard model are predicted.
