Constraining Quintessential Inflation with ACT: A Gauss-Bonnet Gateway

Imtiyaz Ahmad Bhat, Mayukh R. Gangopadhyay, M. Sami, Yogesh

Non-minimal Gauss-Bonnet couplings shift quintessential inflation predictions to match ACT's higher scalar spectral index.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

the exponential and sech-type couplings can shift the predicted values of r and ns into the 1σ region allowed by ACT, thereby restoring consistency with observations

C2weakest assumption

The three chosen functional forms for the scalar-Gauss-Bonnet coupling are representative, and the model-independent reheating parametrization remains valid even without a potential minimum.

C3one line summary

Einstein-Gauss-Bonnet corrections with exponential or sech couplings shift quintessential inflation into the 1 sigma ACT region for r and ns, while tanh coupling remains disfavored.
