  Fast simulation tools are highly appreciated in particle physics
phenomenology studies, especially in the exploration of the physics potential
of future experimental facilities. The Circular Electron Positron Collider is a
proposed Higgs and Z factory that can precisely measure the Higgs boson
properties and the electroweak precision observables. A fast-simulation toolkit
dedicated to the CEPC detector has been developed using Delphes. The comparison
shows that this fast simulation tool is highly consistent with the full
simulation, on a set of benchmark distributions. Therefore, we recommend this
fast simulation toolkit for CEPC phenomenological investigations.
