论文摘要
CDF合作最近对$ W $质量的高精度测量值为$ 7.0〜σ $与标准模型期望不同意。如果$ w $ boson在高能量时具有非平凡的右手量规耦合，则这种张力将缓解。在TEV尺度上，SM量规对称四边形相互作用会诱导右手量规耦合，而SM fermions则组成了庞大的复合颗粒。我们研究了自发对称性破坏产生的顶级质量，并计算$ W $和$ Z $玻色子传播器和衰减。对其质量和宽度的右手耦合校正与实验测量相一致。我们讨论如何在TEV尺度上恢复具有平等的规格对称性的SM量规玻色子和复合颗粒。
The CDF collaboration's recent high-precision measurement of the $W$mass is in $7.0~σ$ disagreement with the Standard Model expectation. This tension will be relieved if the $W$ boson has a non-trivial right-handed gauge coupling at high energies. At TeV scales, the SM gauge symmetric four-fermion interactions induce a right-handed gauge coupling, and SM fermions compose massive composite particles. We investigate the top-quark mass produced by spontaneous symmetry breaking and compute the $W$ and $Z$ boson propagators and decays. The right-handed coupling corrections to their masses and widths are consistent with experimental measurements. We discuss how SM gauge bosons and composite particles can restore parity-preserving gauge symmetries at TeV scales.
