Electroweak Radiative Effects and Hadronic Structure

谁不想知道我们这个世界的基本构成及其相互作用的方式呢？核物理和粒子物理学正是研究这一点的。根据粒子物理的标准模型，有六种夸克，六种轻子，以及通过四种基本相互作用联系起来的相应的反粒子。然而，最近来自中微子振荡、暗物质和暗能量以及量子引力的证据表明，40年前的标准模型可能是不完整的，我们可能正处于一种新理论和新物理的门槛上。寻找新物理可能信号的一种方法是在较低能量下进行高精度实验，这可以提供多TeV尺度的间接物理途径，并对大型强子对撞机研究计划起到重要的补充作用。这项研究需要实验和理论两方面的努力，而新一代实验将需要从理论上达到新的精度。

Who would not want to know the basic constituents of our world and the way they interact? Nuclear and particle physics studies exactly that. According to the Standard Model of particle physics, there are six types of quarks, six types of leptons, and corresponding anti-particles connected by four fundamental interactions. However, the recent evidence coming from neutrino oscillation, dark matter and dark energy, and quantum gravity showed that the 40-year old Standard Model may be incomplete, and that we may be at the threshold of a new theory and "New Physics". One way to look for possible signals of new physics is with high-precision experiments at lower energy which can provide indirect access to physics at multi-TeV scales and play an important complementary role to the Large Hadron Collider research program. This research requires both experimental and theoretical effort, and the new-generation experiments will need a new degree of precision from theory.
