Black Hole Superpartners and Fixed Scalars
Renata Kallosh, Andrei Linde
TL;DR
This paper explores the superpartners of stringy black holes in supergravity, revealing that fixed scalars remain unchanged in superpartners, which could have phenomenological implications.
Contribution
It demonstrates that fixed scalars of black hole superpartners are identical to those of the original black holes, despite supersymmetry transformations.
Findings
Fixed scalars remain unchanged in black hole superpartners.
Superpartners influence the metric and graviphoton.
Phenomenological implications are discussed.
Abstract
Some bosonic solutions of supergravities admit Killing spinors of unbroken supersymmetry. The anti-Killing spinors of broken supersymmetry can be used to generate the superpartners of stringy black holes. This has a consequent feedback on the metric and the graviphoton. We have found however that the fixed scalars for the black hole superpartners remain the same as for the original black holes. Possible phenomenological implications of this result are discussed.
