In three WIMP models, blind spots and loop corrections keep spin-independent scattering below current bounds and, in parts of parameter space, below the neutrino floor, while satisfying thermal relic density.

abstract
The singlet-doublet model is an economical model of weakly interacting dark matter. We revisit it in light of improved dark matter direct detection limits. We characterize the now well-defined regions of remaining parameter space with suppressed direct detection cross sections and discuss features of the spectrum accessible at the Large Hadron Collider. We discuss when and how parameters in these special regions might be realized as the result of renormalization group evolution when starting with generic ultraviolet initial conditions.

WIMPs Below the Radar: Blind Spots and Benchmarks Beyond the Neutrino Floor
In three WIMP models, blind spots and loop corrections keep spin-independent scattering below current bounds and, in parts of parameter space, below the neutrino floor, while satisfying thermal relic density.
