\begin{document}$ {\cal O}(10^{15}) $\end{document} GeV, leading to issues with the proton decay rate. In our analysis, we introduce a novel parameter space that alleviates the proton decay issue by achieving \begin{document}$ M \sim 10^{16} $\end{document} GeV with \begin{document}$ M_{S}^{2}<0 $\end{document} and \begin{document}$ am_{3/2}>0 $\end{document}. This scenario necessitates a soft SUSY breaking scale \begin{document}$ |M_{S}| \gtrsim 10^{6} $\end{document} GeV. Further, we find that the tensor-to-scalar ratio r spans from \begin{document}$ 10^{-16} $\end{document} to \begin{document}$ 10^{-6} $\end{document}, indicating a very small value. This small ratio allows the modified swampland criteria to hold, although satisfying the trans-Planckian censorship conjecture (TCC) remains challenging. To address this, we also explo non-minimal Kähler potentials. By fixing the spectral index at \begin{document}$ n_{S}=0.9665 $\end{document}, consistent with the central value of Planck 2018 data, and setting \begin{document}$ M=2\times 10^{16} $\end{document}GeV, we present our calculations. We show that the canonical measure of primordial gravitational waves, r, for \begin{document}$ M_{S}= $\end{document} 1 TeV, \begin{document}$ m_{3/2}= $\end{document} 1 TeV, and \begin{document}$ \kappa_{S}<0 $\end{document} for \begin{document}$ {\cal{N}}= $\end{document}1 and \begin{document}$ {\cal{N}}= $\end{document}2, ranges from \begin{document}$ 10^{-5} $\end{document} to \begin{document}$ 0.01 $\end{document}, rendering it detectable by Planck and upcoming experiments such as LiteBIRD, Simons Observatory, PRISM, PIXIE, CORE, CMB-S4, and CMB-HD. Additionally, we outline the parametric space and provide benchmark points for the non-minimal case to ensure compatibility with both the modified swampland conjecture and TCC."> Supersymmetric hybrid inflation in light of CMB experiments and swampland conjectures -
