Bound States in Lee's Complex Ghost Model
Ichiro Oda
Quantum field theories (QFTs) including fourth derivative terms such as the Lee-Wick finite QED and quadratic gravity have a better ultra-violet behavior compared to standard theor…
BRST Formalism of Weyl Conformal Gravity
Ichiro Oda, Philipp Saake
We present the BRST formalism of a Weyl conformal gravity in Weyl geometry. Choosing the extended de Donder gauge-fixing condition (or harmonic gauge condition) for the general coo…
Vanishing Noether Current in Weyl Invariant Gravities
Ichiro Oda
We revisit the issue that the Noether current associated with a local scale symmtery, or equivalently the Weyl symmetry, identically vanishes. Based on only the second Noether theo…
Quantum Theory of Weyl Invariant Scalar-tensor Gravity
Ichiro Oda
We perform a manifestly covariant quantization of a Weyl invariant, i.e., a locally scale invariant, scalar-tensor gravity in the extended de Donder gauge condition (or harmonic ga…
Quantum Scale Invariant Gravity with de Donder Gauge
Ichiro Oda
We perform the manifestly covariant quantization of a scale invariant gravity with a scalar field, which is equivalent to the well-known Brans-Dicke gravity via a field redefinitio…
Scale Invariance and Dilaton Mass
Ichiro Oda
We consider a generic scale invariant scalar quantum field theory and its symmetry breakdown. Based on the dimension counting identity, we give a concise proof that dilaton is exac…
