Resumo
It is known that the Maxwell theory in D dimensions can be written in a first-order form (in derivatives) by introducing a totally antisymmetric field which leads to a (D-3)-form dual theory. Remarkably, one can replace the antisymmetric field by a symmetric rank-two tensor (Wμν=W νμ). Such master action establishes the duality between the Maxwell theory and a fourth-order higher-rank model in a D-dimensional flat space-time. A naive generalization to the curved space shows a connection between the recently found D=4 critical gravity and the Maxwell-theory plus a coupling term to the Ricci tensor (RμνAμAν). The mass of the spin-1 particle which appears in the D=4 critical gravity linearized around anti-de Sitter space is the same one obtained from the Ricci coupling term. We also work out, in flat space-time, the explicitly massive case (Maxwell-Proca) which is dual to a second-order theory for Wμν. © 2011 American Physical Society.
