我们认为标准模型，包括一个轻标量玻色子h，是在弱标度v= 246 GeV的一些未知的电弱对称性破缺动力学的有效理论。这种动力学可能很强，h以伪戈德斯通玻色子的形式出现。对称性破缺尺度Λ取为4 π v或以上。我们在这个框架内，这是nonrenormalizable一般的领导阶拉格朗日。然后可以基于循环展开来构造手征拉格朗日量。一个系统的功率计数的推导和使用，以确定出现在一个循环顺序的counterterterms类。利用这一结果，构造了次首阶的完全拉格朗日量，O（v 2/Λ 2）。这个拉格朗日量是包含轻标量玻色子的标准模型的最一般有效的描述，通常具有电弱对称性破缺的强动力学。场景，如SILH anomaly或6维拉格朗日的线性实现希格斯部门可以恢复为特殊情况。
Abstract We consider the Standard Model, including a light scalar boson h, as an effective theory at the weak scale v= 246 GeV of some unknown dynamics of electroweak symmetry breaking. This dynamics may be strong, with h emerging as a pseudo-Goldstone boson. The symmetry breaking scale Λ is taken to be at 4 π v or above. We review the leading-order Lagrangian within this framework, which is nonrenormalizable in general. A chiral Lagrangian can then be constructed based on a loop expansion. A systematic power counting is derived and used to identify the classes of counterterms that appear at one loop order. With this result the complete Lagrangian is constructed at next-to-leading order, O (v 2/Λ 2). This Lagrangian is the most general effective description of the Standard Model containing a light scalar boson, in general with strong dynamics of electroweak symmetry breaking. Scenarios such as the SILH ansatz or the dimension-6 Lagrangian of a linearly realized Higgs sector can be recovered as special cases.
