摘要

研究了在紧致大额外维存在下电弱对称顶凝聚破缺的极小模型。结果表明，由于规范耦合和汤川耦合的幂律演化，Bardeen、Hill和Lindner对顶夸克质量的原始预测大大降低，即使在几个TeV的小截止尺度Λ上，也可以得到实验允许的值。

Top-quark mass in the minimal top-condensation model with extra dimensions

The minimal model of dynamical electroweak-symmetry breaking through top condensation in the presence of compact large extra dimensions is studied. It is shown that, owing to the power-law evolution of gauge and Yukawa couplings, the original predictions of Bardeen, Hill, and Lindner for the top-quark mass are significantly lowered and that, even for a small cutoff scale Λ of a few TeV, one can obtain experimentally allowed values.
