Four seminars of special topics at an accessible level were organized at 4:00 - 5:00pm each afternoon. Prof. Shufang Su of the University of Arizona gave the first seminar on the ''Dark matter search and the LHC". Prof. Tao Han of the University of Wisconsin-Madison spoke on the ''Methodology of collider phenomenology" on the second day. Prof. Hsiang-Nan Li of the Academia Sinica, Taipei, gave a talk on the ''Perturbative QCD and the factorization Theorem". Prof. Lian-Tao Wang finished up in the last day to speak on the ''Monte Carlo techniques in high energy physics".

每个下午16：00-17：00是专题讲座时间，分别由美国亚利桑那大学的苏淑芳教授做了有关"寻找暗物质与LHC"的讲座，美国威斯康星-麦迪逊大学的韩涛教授做了有关"对撞机现象学研究的方法"的讲座，台湾中央研究员的李湘楠教授做了"微扰QCD和因子化定理"的讲座，王连涛教授最后做了"高能物理中的蒙特卡洛方法"的讲座。

Now, a new Fermilab experiment called DAMIC is searching for light dark matter candidates with masses less than that of a proton [1 GeV/c 2 ] or two.

现在，一个新的费米实验室的实验要求DAMIC正在寻找暗物质光线候选人群众小于质子[ 1电子伏特/炭2 ]或两个。

The existence of dark matter is inferred from the behavior of faraway galaxies, which move in ways that can only be explained by a gravitational pull caused by more mass than can be seen.

据物理学家介绍，目前他们只能对宇宙中大约5%的暗物质进行探测。物理学家是根据遥远星系的行为探知暗物质存在的。

A galaxy is a system of many stars and gas that is gravitationally bound in a dark matter halo.

星系是许多恒星和气体构成的系统，在一个暗晕里面通过引力束缚在一起。

We define a first galaxy as one comprised of the very first system of stars to be gravitationally bound in a dark matter halo.

我们这样来定义第一代星系，即由非常早期的恒星系统在暗晕中被引力束缚在一起。

The dark matter only interacts gravitationally and so it stays at the center of the sound wave, the origin of the overdensity.

暗物质仅通过引力进行相互作用，所以其呆在声波的中心，也即声波起源的高密度区域。

Hendrik Hoekstra, also of University of Victoria."This would be the first time we've seen such a thing and could be a huge test of our knowledge of how dark matter behaves."

Hendrik Hoekstra说，他也是维多利亚大学的博士，"我们都一次见到这样的事，它对我们对暗物质的行为的认知是一个巨大的考验"

The time signature of dark matter reionisation will be different from that brought about by stars, says Hooper.

签字的时候，暗物质reionisation将不同于所带来星说，胡珀

So, imaginatively, it was called dark matter.
