Phenomenological implications of strongly-coupled extensions of the Standard Model

以新的强耦合动力学为核心的粒子物理标准模型的扩展代表了一种可能产生令人满意的层级问题解决方案的背景。然而，由于它们的强耦合性质，这些提议也从可预测性的角度提出了挑战，因为传统的微扰计算不可信。有效场论和格子技术的协同结合，再加上规范/重力二元性的思想，提供了一个前所未有的机会，可以在制定不受微调的标准模型的现实扩展方面取得进展。

Extensions of the standard model of particle physics in which new strongly-coupled dynamics plays a central role represent a context that may yield a satisfactory solution of the hierarchy problem. Because of their strongly-coupled nature, though, such proposals also present a challenge from the point of view of predictivity, as traditional perturbative calculations cannot be trusted. The synergetic combination of effective field theory and lattice techniques, together with the ideas of gauge/gravity dualities offers an unprecedented opportunity to make progress towards the formulation of a realistic extension of the standard model that is free from fine-tuning.
