Gauge fields, strings and phenomenology II

现代粒子理论正站在一个十字路口。最近的实验数据相当精确地证实了粒子物理学的基本理论结构——即“标准模型”（SM）。然而，宇宙学最近取得的巨大进展表明，尽管它取得了成功，但在宇宙尺度上仍有很多东西无法解释，例如暗物质。这种对比，再加上一些理论上的不足，导致了一种随之而来的感觉，即更多的事情即将到来，我们期待着在2009年大型强子对撞机开始全面运行时，揭开这个故事的一部分。这样一幅矛盾的图景引导我们向内看，深入研究SM的主要结构，以更好地理解它的成功；向外看，推动能量尺度（和精度）的界限，寻求新物理学的前沿。这种双重观点推动了我研究的主要目标。

Modern particle theory stands at a crossroads. Recent experimental data has led to a rather precise confirmation of the basic theoretical structure for particle physics - namely the `Standard Model' (SM). However, the tremendous recent advances in cosmology show that, despite its success, there is much that the SM cannot explain on cosmological scales, e.g. dark matter. This contrast, combined with several theoretical inadequacies, leads to an ensuing sense that much more is to come and we look forward to the unveiling of part of this story when the LHC collider begins full operations in 2009. Such a conflicted picture directs us to look both inward, to delve into the primary structures of the SM to better understand its success, and outward, to push the boundaries in energy scale (and precision) seeking the frontier at which new physics will become visible. This dual viewpoint drives the primary goals of my research.
