With one new tuned parameter, the paper claims a single supersymmetric phase transition can explain both Type Ia and core-collapse supernovae, heavy element production, and the black hole mass gap.

abstract
We pursue the investigation of a model for sub-Chandrasekhar supernovae Ia explosions (SNIa) in which the energy stored in the Pauli tower is released to trigger a nuclear deflagration. The simplest physical model for such a degeneracy breakdown is a phase transition to an exactly supersymmetric state in which the scalar partners of protons, neutrons, and leptons become degenerate with the familiar fermions of our world as in the supersymmetric standard model with susy breaking parameters relaxed to zero. We focus on the ability of the susy phase transition model to fit the total SNIa rate as well as the delay time distribution of SNIa after the birth of a progenitor white dwarf. We also study the ejected mass distribution and its correlation with delay time. Finally, we discuss the expected SNIa remnant in the form of a black hole of Jupiter mass or lower and the prospects for detecting such remnants.

Extending the susy model to core-collapse supernovae
With one new tuned parameter, the paper claims a single supersymmetric phase transition can explain both Type Ia and core-collapse supernovae, heavy element production, and the black hole mass gap.
