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.

新的强耦合动力学起着核心作用的粒子物理学标准模型的扩展代表了一个可能产生层次问题的满意解决方案的背景。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。有效场论和格点技术的协同结合，以及规范/引力对偶的思想，提供了一个前所未有的机会，朝着制定一个现实的扩展标准模型，是免费的微调取得进展。
