Physical nonviability of $f (Q)$ in the scalar-tensor representation

Jose BeltrÃ¡n JimÃ©nez, Alejandro JimÃ©nez Cano, Tomi S. Koivisto

The authors demonstrate that the scalar‑tensor representation of f(Q) gravity inevitably contains a propagating ghost degree of freedom, confirming its physical non‑viability.
