The following decade is crucial for our understanding of the fundamental structure of elementary particles and forces. The Large Hadron Collider Run 2 is already taking data at unprecedented center-of-mass energy of 13 TeV, which could in a nearest future uncover principally new phenomena such as the extra space dimensions, supersymmetry, etc. On the other hand increasing accuracy of the low-energy experiments allows for a very accurate determination of the fundamental parameters of particle physics and becomes competitive in probing new physics beyond the standard model of particle interactions. In most cases the new physics may show up as a tiny deviation from the theoretical predictions based on the standard model. Thus the high precision of the predictions becomes mandatory.

接下来的十年对我们理解基本粒子和力的基本结构至关重要。大型强子对撞机Run 2已经以前所未有的13 TeV的质心能量采集数据，这可能在不久的将来发现主要的新现象，如额外的空间维度，超对称等。另一方面，低能实验精度的提高使粒子物理的基本参数得到非常精确的确定，并在探索超越粒子相互作用标准模型的新物理方面具有竞争力。在大多数情况下，新物理学可能会表现为与基于标准模型的理论预测的微小偏差。因此，预测的高精度就变得必不可少了。
