Non-abelian cubic vertices for higher-spin fields in anti-de Sitter space | | Nicolas Boulanger

29 Nov 2012 | | Abstract: | We use the Fradkin-Vasiliev procedure to construct the full set of
non-abelian cubic vertices for totally symmetric higher spin gauge fields in
anti-de Sitter space. The number of such vertices is given by a certain
tensor-product multiplicity. We discuss the one-to-one relation between our
result and the list of non-abelian gauge deformations in flat space obtained
elsewhere via the cohomological approach. We comment about the uniqueness of
Vasiliev’s simplest higher-spin algebra in relation with the (non)associativity
properties of the gauge algebras that we classified. The gravitational
interactions for (partially)-massless (mixed)-symmetry fields are also
discussed. | | Source: | arXiv, 1211.6979 | | Services: | Forum | Review | PDF | Favorites | |
