Weyl gravity with a broken SO(1,N) scalar isometry produces pole inflation whose predictions vary with a parameter a, which also fixes the Weyl gauge boson mass and allows a ~10 MeV Weyl photon dark matter candidate.
Thus, for a = [0, 1], the T α-attractor models vary by α = [1, 1 2 ]

The pole inflation from broken non-compact isometry in Weyl gravity
Weyl gravity with a broken SO(1,N) scalar isometry produces pole inflation whose predictions vary with a parameter a, which also fixes the Weyl gauge boson mass and allows a ~10 MeV Weyl photon dark matter candidate.
