Holographic approach to deformations of NS5-brane distributions and exact CFTs
Angelos Fotopoulos, P. Marios Petropoulos, Nikolaos Prezas +1
We consider general planar deformations of a circular distribution of NS5-branes. The near-horizon region of the latter admits, after a T-duality transformation, an exact conformal…
Higher-Spin Gauge Fields Interacting with Scalars: The Lagrangian Cubic Vertex
A. Fotopoulos, N. Irges, A. C. Petkou +1
We apply a recently presented BRST procedure to construct the Largangian cubic vertex of higher-spin gauge field triplets interacting with massive free scalars. In flat space, the…
Interacting Higher Spins and the High Energy Limit of the Bosonic String
A. Fotopoulos, M. Tsulaia
In this note, we construct a BRST invariant cubic vertex for massless fields of arbitrary mixed symmetry in flat space-time. The construction is based on the vertex given in bosoni…
