Phenomenological implications of strongly-coupled extensions of the Standard Model

以新型强耦合动力学为中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次问题解的环境。然而，由于它们的强耦合性质，这些建议也从预测性的角度提出了挑战，因为传统的微扰计算是不可信的。有效场论和晶格技术的协同结合，以及规范/重力对偶性的思想，提供了一个前所未有的机会，可以在制定标准模型的现实扩展方面取得进展，而不需要微调。

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.
