Performance study of the full hadronic WW and ZZ events’ separation at the CEPC
Abstract The full hadronic WW and ZZ events’ separation is an important benchmark for the Circular Electron Positron Collider (CEPC) detector design and reconstruction algorithm development. This separation performance is determined by the intrinsic boson mass distributions, the detector performance...
