Abstract：
Being the heart of the Standard Model of Particle Physics, the Higgs field is deeply associated with many profound mysteries, including the origin of mass, the origin of matter, and the nature of dark matter.
An electron positron Higgs factory that could precisely measure the property of Higgs boson is therefore regarded as the focus and even the top priority for the future exploration of Particle Physics.
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.
For the mankind, the CEPC could well be the gateway towards the propound physics principles underneath the Standard Model.
The reconstruction, especially the reconstruction towards the hadronic system, is critical for the science at CEPC. This talk will report two general aspects of CEPC reconstruction, the Particle Flow that pursues the 1-1 correspondence between reconstructed particle and those actually generated in the detector, and the jet origin identification that aims to identify the origin quark or gluon that cascades into jets. The impact of those tools on the physics is also discussed.
