Fully supersymmetric CP violations in the kaon system

TL;DR

This paper demonstrates that fully supersymmetric CP violations in the kaon system can occur via gluino-mediated interactions, accommodating key observables without fine-tuning or conflicting with constraints.

Contribution

It shows that supersymmetric CP violations are possible through gluino interactions, challenging previous claims and avoiding fine-tuning.

Findings

Both ε_K and Re(ε'/ε_K) can be explained with large tanβ.

No fine-tuning needed for supersymmetric CP violation explanations.

Results are consistent with FCNC and EDM constraints.

Abstract

We show that, on the contrary to the usual claims, fully supersymmetric CP violations in the kaon system are possible through the gluino mediated flavor changing interactions. Both $\epsilon_K$ and ${\rm Re} (\epsilon' / \epsilon_K)$ can be accommodated for relatively large $\tan\beta$ without any fine tunings or contradictions to the FCNC and EDM constraints.
