Olaf Hohm, Jan Louis
TL;DR
This paper investigates spontaneous supersymmetry breaking from N=2 to N=1 in three-dimensional supergravity, focusing on the topological Higgs mechanisms and the resulting effective theories.
Contribution
It introduces a detailed analysis of the topological Higgs and super-Higgs mechanisms in 3D supergravity models with N=2 to N=1 breaking, including spectrum and effective action.
Findings
Identification of the topological Higgs mechanism in 3D supergravity
Derivation of the N=1 spectrum after breaking
Explicit form of the effective action for the broken phase
Abstract
We study models of spontaneous N=2 -> N=1 supergravity breaking in three space-time dimensions and discuss the topological Higgs- and super-Higgs mechanism which generates the masses for the spin-3/2 gravitino multiplet. The resulting N=1 spectrum and its effective action is analysed.
