摘要:

CDF合作组对E_6大统一理论模型中出现的Z'玻色子的质量设定了下限。我们重新审视他们的分析,并将其扩展到某些其他的E_6场景,以及一些一般类的模型满足异常取消条件,这是不包括在CDF分析。我们还提出了一种贝叶斯统计方法,用于寻找Z'质量的排除极限,这使得人们能够探索U(1)'规范耦合参数的宽范围。该方法还考虑了Z'和SM规范玻色子之间的干涉效应。

英文摘要:

The CDF collaboration has set lower limits on the masses of the Z' bosons occurring in a range of E_6 GUT based models. We revisit their analysis and extend it to certain other E_6 scenarios as well as to some general classes of models satisfying the anomaly cancellation conditions, which are not included in the CDF analysis. We also suggest a Bayesian statistical method for finding exclusion limits on the Z' mass, which allows one to explore a wide range of the U(1)' gauge coupling parameter. This method also takes into account the effects of interference between the Z' and the SM gauge bosons.
