abstract
We identify models of supersymmetric hybrid inflation in which the tensor-to-scalar ratio, a canonical measure of gravity waves produced during inflation, can be as large as 0.03 or so, which will be tested by the Planck satellite experiment. The scalar spectral index lies within the WMAP one sigma bounds, while $|d n_s / d\ln k| \lesssim 0.01$.

Supersymmetric Hybrid Inflation with K\"{a}hler-Induced $\mathbf{R}$-Symmetry Breaking
Nonrenormalizable R-symmetry breaking in the Kahler potential can tune the spectral index of supersymmetric hybrid inflation into the ACT DR6 window while keeping tensor modes below 1e-5.

Split supersymmetry and hybrid inflation in light of Atacama Cosmology Telescope DR6 data
An update of mu-term hybrid inflation shows that a tuned soft-SUSY parameter B makes the scalar spectral index match ACT DR6, with tensor-to-scalar ratio of order 10^-3 to 10^-2 and a 2 TeV wino dark matter candidate.
