The Circular Electron Positron Collider, proposed right after the Higgs discovery, is one of these electron positron Higgs factories. In the latest design, it is expected to deliver 4 million Higgs bosons, hundreds of Millions of W bosons, 4 Tera Z bosons, and potentially also 1 million top quarks in an extremely clean collision environment.
The CEPC could well be the gateway towards the propound physics principles underneath the Standard Model, and possibly shed light on many of the profound mysteries, including the origin of mass, the origin of matter, and the nature of dark matter.
The reconstruction, especially the reconstruction towards the hadronic system, is critical for the science at electron positron Higgs factory. This talk presents two corner stones of CEPC reconstruction, the Particle Flow that pursues the 1-1 correspondence between reconstructed particle and final state particles, and the jet origin identification that aims to identify the origin quark or gluon that cascade into jets. The impact of those tools on the physics is also discussed.
Personal CV:
1999 – 2003 - Bachelor Degree on Biomedical Engineering, Tsinghua University
2003 – 2008 - Ph.D Degree on Physics, Tsinghua University and Paris XI University (France)
2008 – 2013 - PostDoc at the Laboratoire Leprince-Ringuet, École Polytechnique (Paris France)
2014 – 2015 - CERN Fellow (Geneva, Switzerland)
2013 – Present - Hundred talent Researcher at Institute of High Energy Physics, Beijing
Being a researcher at the Institute of High Energy Physics, Chinese Academy of Science, I focus on the physics and detector studies for the Circular Electron Positron Collider (CEPC), a proposed gigantic future Higgs/Z factory. I am responsible for the CEPC physics potential analysis, the detector design - optimization, and the reconstruction algorithm/software development.
