Metastable Dark Energy on the Phantom Brane

Recent DESI observations hint at a preference for dynamical dark energy with an equation of state (EoS) that crosses the phantom divide at $w=-1$. In this work, we investigate \textit{metastable} dark energy (DE) on the minimal phantom brane. Braneworld effects lead to $w < -1$ at early times, where
