“…This produces inequivalent gaugings in a definite range, to be determined for each gauge group 4 (for SO(8) c models c ∈ [0, √ 2−1], for SO(6,2) c models we expect c ∈ [0, 1]). As noted in [6], [20][21][22][23], [29], [18], varying c also varies the structure of the scalar potential and the number of critical points. For the SO(6,2) c models, the analysis of [26] shows that there is a Minkowski vacuum at c = 1, which disappears for c = 1 (which explains why it was not found in the c = 0 model discussed in [40], [42]).…”
