The random-field Ising model's SUSY/DR fixed point annihilates with an unstable fixed point at d_DR ≈ 5.11 ± 0.09, so no SUSY/DR critical point survives below this dimension in the nonperturbative FRG.

On the breakdown of dimensional reduction and supersymmetry in random-field models
The random-field Ising model's SUSY/DR fixed point annihilates with an unstable fixed point at d_DR ≈ 5.11 ± 0.09, so no SUSY/DR critical point survives below this dimension in the nonperturbative FRG.
