Warped super-bigravity

TL;DR

This paper discusses warped supergravity models with branes, focusing on supersymmetry properties, including unbroken and broken supersymmetry scenarios, within a consistent field-theoretic framework relevant to string theory.

Contribution

It introduces two locally supersymmetrized bigravity models, one with unbroken N=1, d=4 supersymmetry and another with broken supersymmetry via boundary conditions.

Findings

Constructed models with unbroken supersymmetry.

Developed models with broken supersymmetry through boundary conditions.

Provided a framework for studying supersymmetry transmission between branes.

Abstract

Warped supergravities with lower-dimensional branes provide consistent field-theoretic framework for discussion of important aspects of modern string theory physics. In particular, it is possible to study reliably supersymmetry breakdown and its transmission between branes. In this talk we present two versions of locally supersymmetrized bigravity - one with unbroken N=1,d=4 supersymmetry, and the second one with all supersymmetries broken by boundary conditions.
