A new spin-2 self-dual model in
D. Dalmazi, E. L. Mendonca
There are three self-dual models of massive particles of helicity +2 (or -2) in . Each model is of first, second, and third-order in derivatives. Here we derive a new self-d…
Generalized soldering of helicity states in
D. Dalmazi, Elias L. Mendonça
The direct sum of a couple of Maxwell-Chern-Simons (MCS) gauge theories of opposite helicities does not lead to a Proca theory in , although both theories share the…
Dual descriptions of spin two massive particles in via master actions
D. Dalmazi, Elias L. Mendonca
In the first part of this work we show the decoupling (up to contact terms) of redundant degrees of freedom which appear in the covariant description of spin two massive particles…
Restrictions over two-dimensional gauge models with Thirring-like interaction
D. Dalmazi, A. de Souza Dutra
Some years ago, it was shown how fermion self-interacting terms of the Thirring-type impact the usual structure of massless two-dimensional gauge theories [1]. In that work only th…
Multiflavor Soldering
D. Dalmazi, A. de Souza Dutra
In two dimensions the simple addition of two chiral bosons of opposite chiralities does not lead to a full massless scalar field. Similarly, in three dimensions the addition of two…
Quantum equivalence between the self-dual and the Maxwell-Chern-Simons models nonlinearly coupled to U(1) scalar fields
D. Dalmazi, Elias L. Mendonca
The use of master actions to prove duality at quantum level becomes cumbersome if one of the dual fields interacts nonlinearly with other fields. This is the case of the theory con…
