Title: Higgs Search at LHC,Most Recent Progress and Results

Speaker: Prof. Chen Mingshui

Abstract:

In this seminar, the latest results about the experimental searches for the Standard Model Higgs at LHC are reviewed. Also combined measurements of the properties of the new state around 125 GeV are shown. These include combined measurements of the mass of the new state as well as its tensor structure (spin, CP) and couplings to other particles.

About the speaker:

Mingshui Chen is currently a Research Associate in University of Florida and working on CMS experiments searching for the Standard Model Higgs and new physics. He played significant role in the discovery of the new boson with mass around 125GeV, in particular on the Higgs combination and H->ZZ->4l channel.

Speech 2:

Title: Top Quark Physics at LHC

Speaker: Prof. Zhang Huaqiao

Abstract：

As the most massive known elemental constituent of matter, the top quark's unexplained large mass suggests an important connection to the still mysterious electroweak symmetry breaking mechanism. Top quark is the basis of links to possible new particle and interactions that could appear at the LHC. This seminar will review our current understanding of top quark, and latest new physics searches with top quark signature.

About the speaker:

Huaqiao ZHANG is a research associate at Michigan State University. Since joined ATLAS group in 2005，he is/was editor and contact editor of four ATLAS physics analysis involved top quark within the content of Higgs physics, top physics and exotic physics. Including the first experimental evidence of single top quark associated with W boson production. He is also heavily involved in the ATLAS Liquid Argon calorimeter performance study, monitoring and optimization since 2007.
