英文摘要	We propose a simplified model to study the possible new heavy diphoton resonance from the cascade decay of a heavier particle at colliders, which may be related to dark matter or other new physics beyond the Standard Model. Model-independent constraints and predictions on the allowed couplings for generating the observed diphoton data are studied in detail. We demonstrate that this scenario can be tested by the possible four-photon signal or the WW/ZZ/Z gamma resonances. Meanwhile, this cascade decay scenario also provides us with dark matter candidates, which is consistent with the observed dark matter relic density.
