Do DESI-DR2 BAO data imply a coupling of dark matter and dark energy?
Aps.org·September 28, 2026
We revisit an interacting dark matter (DM)-dark energy (DE) model characterized by the interaction function $Q=\mathrm{\ensuremath{\Gamma}}{\ensuremath{\rho}}_{x}$, where $\mathrm{\ensuremath{\Gamma}}$ is a constant coupling parameter and ${\ensuremath{\rho}}…
