We consider the generic scalar potential with CP-violation, and study the $Z$resonance and inelastic dark matter in the Simple Extension of the StandardModel (SESM), which can explain the dark matter as well as new physicsanomalies such as the B physics anomalies and muon anomalous magnetic moment,etc. With the new scalar potential terms, we obtain the mass splittings for thereal and imaginary parts of scalar fields. And thus we can have the DMco-annihilation process mediated by $Z$ boson, which couples exclusively to theCP-even and CP-odd parts of scalar fields. This is a brand new feature comparedto the previous study. For the CP conserving case, we present the viableparameter space for the Higgs and $Z$ resonances, which can explain the Bphysics anomalies, muon anomalous magnetic moment, and dark matter relicdensity, as well as evade the constraint from the XENON1T direct detectionsimultaneously. For the CP-violating case, we consider the inelastic darkmatter, and study four concrete scenarios for the inelastic DM-nucleonscatterings mediated by the Higgs and $Z$ bosons in details. Also, we presentthe benchmark points which satisfy the aforementioned constraints. Furthermore,we investigate the constraints from the dark matter-electron inelasticscattering processes mediated by the Higgs and $Z$ bosons in light of theXENONnT data. We show that the constraint on the $Z$ mediated process is weak,while the Higgs mediated process excludes the dark matter with mass aroundseveral MeV.
