Every Poincaré gauge theory is conformal: A compelling case for dynamical vector torsion
The Poincaré gauge theory (PGT) of gravity provides a viable formulation of general relativity (Einstein–Cartan theory), and a popular model-building framework for modified gravity with torsion. Notoriously, however, the PGT terms which propagate vector torsion lead to strongly-coupled ghosts: the m...
