摘要：

我们构造有效的拉格朗日量，和相应的计数计划，有效地描述最低的躺在大N稳定的大质量复合态出现在强耦合理论的动力学。当通过有效的拉格朗日描述计算量子修正时，现在可以采用大N计数规则。该框架允许系统的调查非戈德斯通性质的复合动力学。相关的例子是杨-米尔斯理论中出现的最轻的胶球态。我们进一步应用有效的方法和相关的计数计划，在电弱尺度的复合模型。为了说明的形式主义，我们认为希格斯出现的可能性：最轻的胶球的一个新的复合理论;大N标量介子模型的动态电弱对称性破缺;大N赝介子也有用的模型的近共形动力学。对于这些实现中的每一个，我们确定了领先的N个修正的电弱精度参数。结果很好地阐明了潜在的大N动力学，并可用于对抗第一原理晶格结果具有复合标量与系统的有效方法。

英文摘要：

We construct effective Lagrangians, and corresponding counting schemes, valid to describe the dynamics of the lowest lying large N stable massive composite state emerging in strongly coupled theories. The large N counting rules can now be employed when computing quantum corrections via an effective Lagrangian description. The framework allows for systematic investigations of composite dynamics of non-Goldstone nature. Relevant examples are the lightest glueball states emerging in any Yang-Mills theory. We further apply the effective approach and associated counting scheme to composite models at the electroweak scale. To illustrate the formalism we consider the possibility that the Higgs emerges as: the lightest glueball of a new composite theory; the large N scalar meson in models of dynamical electroweak symmetry breaking; the large N pseudodilaton useful also for models of near-conformal dynamics. For each of these realisations we determine the leading N corrections to the electroweak precision parameters. The results nicely elucidate the underlying large N dynamics and can be used to confront first principle lattice results featuring composite scalars with a systematic effective approach.
