After the Higgs discovery, the precise determination of the Higgs boson properties became one of the top priorities for the experimental particle physics. The Circular Electron Positron Collider is one of these proposed future Higgs factories. Colliding the electron and positron at a tunnel with main ring circumference of 100 km, the CEPC is expected to deliver 1 Million Higgs bosons in an extremely clean collision environment. In addition, the CEPC also produces 100 Million W bosons and nearly 1 Tera Z bosons, enabling precise EW measurement, Flavor measurements, and QCD.
The rich physics program at the CEPC makes stringent requirements on the detector performance. This report outlines the basic idea to quantify the requirements for the CEPC detector design and reports the corresponding performance achieved at the CEPC Baseline detector.
