Theory 105/New facility/Dark matter
Neutrino Floor
The claim
Direct detection of weakly interacting dark matter below the neutrino floor requires a directional detector, because the neutrino background is otherwise irreducible.
01Mechanism
Neutrino recoils mimic the signal; direction distinguishes them.
02Prediction
Sensitivity should stall without directional information.
03Refutation
Background separable without direction would remove the need.
