The so-called lattice approach is a very successful first principle method that allows to solve Gauge Theories. Calculations resort to large scale simulations and are typically run on the largest supercomputers. Lattice simulations are a unique tool to explore non perturbative phenomena in theories which are not well understood. In Nature, non perturbative phenomena give rise to the mass of the ordinary proton, whose mass mostly come from the binding energy of its constituents : the quarks. Tremendous efforts are being made to design extensions of the Standard Model of particle physics using similar mechanism that could for instance explain the mass and properties of the Higgs boson. The project aims at making the first prediction of decay rates of resonances relevant for phenomenological analysis beyond the Standard Model using lattice simulations, and will thus provide quantitative results that are relevant for experiments searching for new physics like the one performed by the world's largest accelerator: the Large Hadron Collider (LHC).

所谓的格点方法是一种非常成功的第一原理方法，可以用来解决规范理论。计算采用大规模模拟，通常在最大的超级计算机上运行。晶格模拟是一个独特的工具，探索理论中的非微扰现象，这是没有很好地理解。在自然界中，非微扰现象产生了普通质子的质量，其质量主要来自其组成部分的结合能：夸克。人们正在做出巨大的努力来设计粒子物理学标准模型的扩展，使用类似的机制，例如可以解释希格斯玻色子的质量和性质。该项目旨在使用晶格模拟首次预测与标准模型之外的唯象分析相关的共振衰减率，从而提供与寻找新物理学的实验相关的定量结果，例如世界上最大的加速器：大型强子对撞机（LHC）。
