电弱有效理论与超标准模型共振

Electroweak effective theory and beyond Standard Model resonances

Juan Jose Sanz-Cillero, Antonio Pich, Ignasi Rosell

摘要:

我们考虑一个非线性实现的电弱破缺模式$SU(2)_L\times SU(2)_R/SU(2)_{L+R}$,以构建一个低能量有效的理论,后来扩展的包含重新物理共振。在假定适当的Weinberg求和规则给出的高能约束和形状因子的渐近行为后,我们得到了共振质量与某些低能有效耦合之间的关系。这些预测与目前的实验数据进行了比较,并推断出一些共振质量的界限。

英文摘要:

We consider a non-linear realization of the electroweak symmetry-breaking pattern $SU(2)_L\times SU(2)_R/SU(2)_{L+R}$ to construct a low-energy effective theory, later extended by the inclusion of heavy new-physics resonances. After assuming appropriate high-energy constraints given by Weinberg sum-rules and the asymptotic behaviour of form-factors, we obtain relations between resonance masses and some low-energy effective couplings. These predictions are compared with current experimental data and some resonance mass bounds are inferred.
