Positive running of the spectral index is achievable in Einstein-Gauss-Bonnet gravity with viable inflation, unlike standard scalar field and F(R) models which face challenges.
MCMC fitting of joint P-ACT-LB-BK18 dataset constrains non-canonical parameter alpha to 8.8, 11.7, and 16.4 (1 sigma) for chaotic inflation potentials with n=1/3, 2/3, 1 respectively.

Constraints on non-canonical chaotic inflation from ACT DR6 and BICEP/Keck data
MCMC fitting of joint P-ACT-LB-BK18 dataset constrains non-canonical parameter alpha to 8.8, 11.7, and 16.4 (1 sigma) for chaotic inflation potentials with n=1/3, 2/3, 1 respectively.
