报告题目：宇宙拼图——从极小到极大
报告人：王萌 教授（山东大学）
报告摘要：
基本粒子标准模型和大爆炸理论是人们研究物质世界两个极端的最成功的理论，它们正日益融合，几乎解释了从夸克和轻子到宇宙大结构和可观测宇宙的所有基本问题。尽管如此，还有若干深刻的问题，有待超越标准模型。大爆炸理论更是再一次在新世纪之初带来了两朵乌云，即暗物质和暗能量，或许，人类对世界的认识又面临一次突破。本报告将简单介绍我们目前对微观极限和宇观极限的了解，并重点介绍对暗物质的认识、实验探测以及正在进行的PandaX实验。

报告题目：Measurements of the Higgs Boson at the Large Hadron Collider at CERN
报告人： Dr. Chunhui Chen（Iowa State University）
报告摘要：
Originally proposed as a theoretical construct in 1964 to explain how an underlying symmetry in a Lagrangian may be hidden in the ground state, the Higgs boson soon became the key stone of the Standard Model in the particle physics. In the years since the Standard Model has been remarkably successful in explaining experimental results and yet, the Higgs boson itself has remained elusive until the advent of the Large Hadron Collider (LHC) at CERN. The discovery at the LHC of the Higgs boson in 2012 has prompted the awarding of the 2013 Nobel prize to Francois Englert and Peter Higgs.
In this talk I will give a brief review on the measurements of the Higgs boson properties at the LHC, with the emphasis on most recent evidence of the Higgs boson decay to a bottom quark-antiquark pair, as well as some selected topics on exotics Higgs decays to dark sector particles. I will finish off by discussing the future prospect of the particle physics in the post Higgs discovery era.
报告人简介：
Dr. Chen is currently an associate professor in the Department of Physics and Astronomy at Iowa State University.
He received his PhD in physics from the University of Pennsylvania in 2003 working on the CDF experiment at the Fermilab. He then joined the University of Maryland as a postdoc and carried out his research on the CP violation at the Stanford Linear Accelerator Center. Since 2009, Dr. Chen has been a faculty at Iowa State University. His current research focus is the ATLAS experiment, one of the two experiments that discovered the Higgs Boson in 2012.
