SUSY R parity violation and CP asymmetry in semi-leptonic tau-decays

TL;DR

This paper investigates CP violation in semi-leptonic tau decays within R-parity violating supersymmetric models, showing potential for enhanced asymmetries detectable by current experiments, indicating new physics beyond the Standard Model.

Contribution

It demonstrates that R-parity violating SUSY models can significantly enhance CP asymmetries in tau decays, making them observable with existing experimental limits.

Findings

CP asymmetry in tau decay can be significantly enhanced by R-parity violation.

Current experimental limits are compatible with the predicted asymmetries.

Observation of CP violation would indicate R-parity violating SUSY as new physics.

Abstract

We analyze the CP violation in the semileptonic | \Delta S|=1 tau-decays in supersymmetric extensions of the standard model (SM) with R parity violating term. We show that the CP asymmetry of tau-decay is enhanced significantly and the current experimental limits obtained by CLEO collaborations can be easily accommodated. We argue that observing CP violation in semi leptonic tau-decay would be a clear evidence for R-parity violating SUSY extension of the SM.
