Description
The (Circular Electron Positron Collider) CEPC is proposed in China, which is one of the most attractive future colliders. It’s also an ideal platform to search for new physics, test the standard model, and research a set of advanced focus in physics as a future Higgs factory. To test Bell inequalities, we construct observable for the H → ZZ∗ process in CEPC through the use of (Collins-Gisin-Linden-Massar-Popescu) CGLMP inequality, which can derive its value from the density matrix of Z boson pairs from di-boson Higgs decay. With the application of Monte Carlo simulations, we study the observable $I_{3}$ of the CGLMP inequality for our signal processes, which provides reliable evidence of Bell inequalities violations. In this study, we investigate and simulate the possible backgrounds on CEPC at a collision energy of 250 GeV.
