AdS$_3$/AdS$_2$ degression of Fronsdal fields

High Energy Physics - Theory 2022-10-19 v2

Abstract

We analyze the Kaluza-Klein type procedure in AdS3_3 space called the dimensional degression. The topological theory of the Fronsdal field in AdS3_3 is reformulated in terms of the fields propagating in AdS2_2. We find that the Fronsdal field in AdS3_3 leads to finitely many Kaluza-Klein modes. Namely, the obtained spectrum is the massive Klein-Gordon and Proca fields in AdS2_2. The result is derived by using the specific mode expansion, the gauge fixing, and 2-dimensional Schouten identities.
