Rare kaon decay $K^+ \rightarrow \pi^- \mu^+ \mu^+$ as the key event for the right-handed weak interaction effects

TL;DR

This paper explores the potential of the rare decay $K^+ ightarrow ext{ extpi}^{-} ext{ extmu}^{+} ext{ extmu}^{+}$ as a key indicator for detecting right-handed weak interaction effects within an extended SU(2) model.

Contribution

It highlights the rare kaon decay as a promising event to observe right-handed weak interactions, providing a new experimental focus for beyond Standard Model physics.

Findings

Rare decay could reveal right-handed weak interactions

Decay observation would support SU(2)$_L$ imes$ SU(2)$_R$ model

Proposes specific decay as a key experimental signature

Abstract

We discuss on the search for the right-handed weak interaction effects in the SU(2)$_L \times$SU(2)$_R$ model with lepton doublets $(\nu_\ell, \ell^-)_L$ and $(N_\ell, \ell^-)_R$ ($\ell = e, \mu, \tau)$. We will point out that only the chance of the observation of the right-handed weak interaction effect will be in the rare decay $K^+ \rightarrow \pi^- \mu^+ \mu^+$.
