报告摘要:

Recent measurements of the Higgs boson properties in the four-lepton channel using

36.1 fb-1 of pp collisions at 13 TeV with the ATLAS detector will be presented. The

measurements include the Higgs boson mass as well as inclusive, fiducial, differential

and, so-called, simplified template cross sections. Constraints on Higgs boson

couplings are derived and interpreted within the Standard Model and various

extensions. Direct searches for new physics using four-lepton and di-lepton plus

missing transverse momentum final states will also be discussed.

   

报告人简介:

Dr. Lailin Xu is an experimental particle physicist, working on the ATLAS experiment

at the Large Hadron Collider. He has been a Postdoctoral Research Associate in

Physics at Brookhaven National Laboratory, after obtaining his PhD in Physics in

2015 from The University of Science and Technology of China. Dr. Xu’s research

interests have been focused on Higgs property and couplings measurements, precision

electroweak gauge boson coupling measurements, and searches for new physics in

diboson final states. He pursues to understand fundamental issues of the Universe,

such as the Electroweak Symmetry breaking and the nature of dark matter. He also

works on R&D of High-voltage CMOS pixel sensors, a novel tracking detector

technology that can be used for the ATLAS Inner Tracker Phase-II upgrade or future

high energy physics experiments.
