Description
We study a simplified scenario in the next-to-minimal supersymmetry standard model where the electroweak sector has a split spectrum with light singlino and higgsinos and the lightest neutralino $\tilde{\chi}_1^0$ is singlino-dominated. Serving as a dark matter candidate, $\tilde{\chi}_1^0$ should have either resonant annihilation effects or sizable higgsino components to satisfy the observed relic abundance. The sensitivities of LHC trilepton and dilepton searches and dark matter detection experiments are investigated. Near future direct and indirect dark matter searches are promising to cover the parameter regions where collider searches lose their sensitivities.
