Higher-derivative massive actions from dimensional reduction
Euihun Joung, Karapet Mkrtchyan
A procedure to obtain higher-derivative free massive actions is proposed. It consists in dimensional reduction of conventional two-derivative massless actions, where solutions to c…
Generating functions of (partially-)massless higher-spin cubic interactions
Euihun Joung, Luca Lopez, Massimo Taronna
Generating functions encoding cubic interactions of (partially-)massless higher-spin fields are provided within the ambient-space formalism. They satisfy a system of higher-order p…
Singular SQCD Vacua and Confinement
Simone Giacomelli, Kenichi Konishi
We revisit the study of confining vacua in the softly broken N=2 supersymmetric QCD, in the light of some recent developments in our understanding of the dynamics of N=2 gauge theo…
On cubic AdS interactions of mixed-symmetry higher spins
L. Lopez
The problem of finding consistent cubic AdS interactions of massless mixed-symmetry higher-spin fields is recast into a system of partial differential equations that can be solved…
Bulk Renormalization and Particle Spectrum in Codimension-Two Brane Worlds
Alberto Salvio
We study the Casimir energy due to bulk loops of matter fields in codimension-two brane worlds and discuss how effective field theory methods allow us to use this result to renorma…
Accidental SUSY: Enhanced Bulk Supersymmetry from Brane Back-reaction
C. P. Burgess, L. van Nierop, S. Parameswaran +2
We compute how bulk loops renormalize both bulk and brane effective interactions for codimension-two branes in 6D gauged chiral supergravity, as functions of the brane tension and…
