Every Poincaré gauge theory is conformal: a compelling case for dynamical vector torsion
Will Barker, Michael Hobson, Anthony Lasenby +2
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…
Ghost and tachyon free Weyl gauge theories: a systematic approach
Yun-Cherng Lin, Michael P. Hobson, Anthony N. Lasenby
We investigate the particle content of parity-preserving Weyl gauge theories of gravity (WGT) about a Minkowski background. Within a subset of the full theory, we use a systema…
Power-counting renormalizable, ghost-and-tachyon-free Poincaré gauge theories
Yun-Cherng Lin, Michael P. Hobson, Anthony N. Lasenby
We present 48 further examples, in addition to the 10 identified in [1], of ghost-and-tachyon-free critical cases of parity-conserving Poincaré gauge theories of gravity (PGT)…
Ghost and tachyon free Poincaré gauge theories: a systematic approach
Yun-Cherng Lin, Michael P. Hobson, Anthony N. Lasenby
A systematic method is presented for determining the conditions on the parameters in the action of a parity-preserving gauge theory of gravity for it to contain no ghost or tachyon…
