英文摘要 | We investigate the projected sensitivity to effective dark matter (DM)-diboson interaction during the high luminosity Z-pole and 240GeV runs at the proposed Circular Electron Positron Collider (CEPC). The proposed runs at the 91.2GeV e(+)e(-) center of mass energy offers an interesting opportunity to probe effective dark matter couplings to the Z boson, which can be less stringently tested in non-collider searches. We investigate the prospective sensitivity for dimension 6 and dimension 7 effective diboson operators to scalar and fermion dark matter. These diboson operators can generate semi-visible Z boson decay, and high missing transverse momentum mono-photon signals that can be test efficiently at the CEPC, with a small and controllable Standard Model gamma(upsilon) over bar nu background. Projected sensitivities for the effective gamma Z coupling efficient kappa(gamma)Z < (1030 GeV)(-3), (1970 GeV)(-3) for scalar DM, kappa(gamma)Z < (360 GeV)(-3), (540 GeV)(-3) for fermion DM are obtain for 25 fb(-1) and 2.5ab(-1) Z-pole luminosities assuming the optimal low dark matter mass range. We also compare the CEPC sensitivities to current direct and indirect search limits on these effective DM-diboson operators. |
