The ultimate goal of particle physics is to find the theory which unifies all the forces and particles in Nature. A first step has been taken with the unification of the electromagnetic and weak forces into a single "electroweak" force. The Standard Model (SM) of particle physics, which includes the electroweak and the strong forces, successfully explains all known experimental data. Nevertheless, it is clearly not the final theory -- only two of the four forces are unified, and the SM leaves many questions unanswered. Thus, there must be "physics beyond the SM," that is, phenomena which cannot be explained by the SM alone. The search for this "new physics" (NP) is the most important problem facing particle physicists today.

粒子物理学的最终目标是找到统一自然界所有力和粒子的理论。第一步是将电磁力和弱力统一为单一的“电弱”力。粒子物理学的标准模型（SM），包括电弱和强作用力，成功地解释了所有已知的实验数据。然而，它显然不是最终的理论——四种力中只有两种是统一的，而且SM留下了许多未解之谜。因此，必然存在“超越SM的物理学”，也就是说，不能仅用SM来解释的现象。寻找这种“新物理学”（NP）是当今粒子物理学家面临的最重要的问题。
