具有Z-γ和电荷的Z'玻色子混合

Z' Boson Mixings with Z-γand Charge Assignments

Ying Zhang, Qing Wang

摘要:

基于从电弱手征拉格朗日量导出的Z '-Z-γ混合的一般描述,我们将文献中出现的各种涉及Z'玻色子的新物理模型刻画和分类为五类:1.具有最小Z '-Z质量混合的模型; 2.具有最小Z '-Z动力学混合的模型; 3.具有一般Z '-Z混合的模型; 4.具有Z '-γ动力学和Z'-Z混合的模型;以及5. Stueckelberg型混合模型。相应的混合矩阵显式评估这些类中的每一个。利用反常抵消条件对Z'玻色子荷进行了约束和分类。

英文摘要:

Based on the general description for Z'-Z-γmixing as derived from the electroweak chiral Lagrangian, we characterize and classify the various new physics models involving the Z' boson that have appeared in the literature into five classes: 1. Models with minimal Z'-Z mass mixing; 2. Models with minimal Z'-Z kinetic mixing; 3. Models with general Z'-Z mixing; 4. Models with Z'-γkinetic and Z'-Z mixing; and 5. Models with Stueckelberg-type mixing. The corresponding mixing matrices are explicitly evaluated for each of these classes. We constrain and classify the Z' boson charges with respect to quark-leptons by anomaly cancellation conditions.
