Recent BICEP/Keck data, combined with previous WMAP and Planck data, provide strong new constraints on the tilt in the scalar perturbation spectrum (n(s)) and the tensor-to-scalar ratio (r). These constraints are evaluated in attractor models of inflation formulated in no-scale supergravity, and they determine the number of e-folds of inflation (N-*), the magnitude of the inflaton coupling to matter (y), and the reheating temperature (T-reh). The 68% C.L. region prefers large values of N-*, y, and T-reh, which are constrained by the production of gravitinos and supersymmetric dark matter.
Recent BICEP/Keck data on the cosmic microwave background, in combination with previous WMAP and Planck data, impose strong new constraints on the tilt in the scalar perturbation spectrum, n(s), as well as the tensor-to-scalar ratio, r. These constrain the number of e-folds of inflation, N-*, the magnitude of the inflaton coupling to matter, y, and the reheating temperature, T-reh, which we evaluate in attractor models of inflation as formulated in no-scale supergravity. The 68% C.L. region of (n(s), r) favors large values of N-*, y, and T-reh, that are constrained by the production of gravitinos and supersymmetric dark matter.
