Does black hole radiance break supersymmetry ?

TL;DR

This paper reexamines whether black hole radiation breaks supersymmetry, showing that careful handling of spinorial parameters may preserve supersymmetry, contrasting earlier claims of its breakdown.

Contribution

It demonstrates that proper treatment of Grassmann variables can prevent supersymmetry breaking in Hawking radiation from black holes.

Findings

Supersymmetry may not break in black hole radiation when Grassmann variables are carefully handled.

Comparison with flat spacetime at finite temperature supports the possibility of unbroken supersymmetry.

Reevaluation challenges previous conclusions about supersymmetry breaking in black hole environments.

Abstract

Arguments presented in an earlier paper, demonstrating the breakdown of global supersymmetry in Hawking radiation from a generic four dimensional black hole with infalling massless scalar and spinor particles, are reexamined. Careful handling of the Grassmann-valued spinorial parameter is shown to lead to a situation wherein supersymmetry may not actually break. A comparative analysis in flat spacetime at a finite temperature, is also presented.
