In three dimensions, there are two distinct mass-generating mechanisms for gauge vector and tensor fields: adding the usual Proca/Pauli-Fierz, or the more esoteric Chern-Simons (CS), terms. Here, we analyze the three-term models where both types are present, and their various limits. Surprisingly, in the tensor case, these seemingly innocuous systems are physically unacceptable. If the sign of ...
متن کاملTopologically Massive Models from Higgs Mechanism
A new variational principle allowing the implementation of the Higgs mechanism for abelian theories over non-trivial background flat connections is proposed. It is found that the mass generated for the spin 1 excitation is the same as the one obtained from the standard Higgs mechanism over trivial backgrounds, however, the dynamical structure of the action for the Higgs scalar is completely dif...
متن کاملDistended Topologically Massive Electrodynamics
We extend topologically massive electrodynamics, both by adding a higher derivative action to cast the entire three-term model in Chern-Simons (CS) form, and by embedding it in an AdS background. It can then be written as the sum of two CS terms, one of which vanishes at the “chiral” point, in analogy with its gravitational topologically massive counterpart. Separately we treat pure CS electrod...
متن کاملRenormalizability of Topologically Massive Gravity
We consider renormalizability of topologically massive gravity in three space-time dimensions. With a usual parametrization of the metric tensor, we establish the statement that topologically massive gravity is in fact renormalizable. In this proof, we make use of not only a recently found, new infrared regularization method of scalar mode but also a covariant ultraviolet regulator with a speci...
