Mechanism
DCT does not contain a particle dark-matter component. Galactic dynamics arise from the Avrami crystallisation profile of the tie field, not from a particle. Predicted spin-independent cross-section is exactly zero.
Derivation
DCT does not contain a particle dark-matter component. Galactic dynamics arise from the Avrami crystallisation profile of the tie field, not from a particle. Predicted spin-independent cross-section is exactly zero.
The closed-form prediction is
$$ \text{predicted} = exactly 0 $$against the measurement all current upper limits (LZ, XENONnT, PandaX), giving residual consistent with 0.
Python verification
The verification script for this observable is astrophysical_tests.py. Run it with python3 astrophysical_tests.py to reproduce the canonical DCT result against the public-archive measurement source listed above (LZ 2024; XENONnT 2024; PandaX-4T 2024.).
