Feng-Jun Ge, Shao-Zhou Jiang, Qing Wang

摘要:

对K.莱恩,它使用非平凡的模式techniquark凝聚和行走,在这项研究中进行了调查。我们发现,该模型的特点是定性相似的那些车道以前的自然TC2原型模型,但没有限制的上限Z'的质量。我们讨论了该模型的相结构和可能的行走行为。我们得到的电弱手征拉格朗日函数的所有系数的值的顺序为p4。我们表明,虽然步行效应减少了S参数的一半,其原始值,它保持了2的顺序。此外,需要一种特殊的超荷安排,以实现其价值的进一步降低。

英文摘要:

The electroweak chiral Lagrangian for the topcolor assisted technicolor model proposed by K. Lane, which uses nontrivial patterns of techniquark condensation and walking, was investigated in this study. We found that the features of the model are qualitatively similar to those of Lane's previous natural TC2 prototype model, but there is no limit on the upper bound of the Z' mass. We discuss the phase structure and possible walking behavior of the model. We obtained the values of all coefficients of the electroweak chiral Lagrangian up to an order of p4. We show that although the walking effect reduces the S parameter to half its original value, it maintains an order of 2. Moreover, a special hyper-charge arrangement is needed to achieve further reductions in its value.
