Nonlinear completion of massive gravity of the Fierz-Pauli type
Shinji Hamamoto
A possible nonlinear completion of massive gravity of the Fierz-Pauli type is proposed. The theory describes a system consisting of a massive tensor field of the Fierz-Pauli type a…
Possible Nonlinear Completion of Massive Gravity
Shinji Hamamoto
Possible nonlinear completion of massive gravity is presented. An additional scalar ghost contained in linear theory condensates to give rise to positive-energy excitations.
Massless Limits of Massive Tensor Fields II --- Infrared regularization of Fierz-Pauli model ---
Shinji Hamamoto
Izawa's gauge-fixing procedure based on BRS symmetry is applied twice to the massive tensor field theory of Fierz-Pauli type. It is shown the second application can remove massless…
Gauge Theory of Massive Tensor Field II --- Covariant Expressions ---
Shinji Hamamoto
Covariant forms are given to a gauge theory of massive tensor field. This is accomplished by introducing another auxiliary field of scalar type to the system composed of a symmetri…
Massless Limits of Massive Tensor Fields
Shinji Hamamoto
In order to construct a massive tensor theory with a smooth massless limit, we apply two kinds of gauge-fixing procedures, Nakanishi's one and the BRS one, to two models of massive…
Higher Derivatives and Canonical Formalisms
Takao Nakamura, Shinji Hamamoto
Path integral expressions for three canonical formalisms -- Ostrogradski's one, constrained one and generalized one -- of higher-derivative theories are given. For each fomalism we…
