In this paper, we focus on the supersymmetric model with left-right (LR) symmetry, that is especially proposed in our previous work [1]. In this model, there are four Higgs doublets in order to realize the Standard Model (SM) fermion masses and the Cabibbo-Kobayashi-Maskawa matrix. The heavy Higgs doublets unavoidably have flavor changing couplings to the SM fermions and induce flavor-changing neutral currents at tree level. We study broader parameter space than the previous work with including the renormalization group corrections to the Yukawa couplings between the LR breaking scale, \( \mathcal{O} \)(10¹³) GeV, and the supersymmetry breaking scales, \( \mathcal{O} \)(100) TeV. The CP violating observable in K–\( \overline{K} \) mixing, ϵ_K, strongly constrains the model, so that heavy Higgs mass should be heavier than \( \mathcal{O} \)(100) TeV. We study the lepton flavor violating (LFV) processes setting heavy Higgs masses to be 170 TeV. The branching ratios of μ → 3e and the μ–e conversion can be larger than 10⁻¹⁶ that could be covered by the future experiments. We also study the degree of fine-tuning in the parameter region that predicts testable LFV processes.

在本文中，我们专注于具有左右（LR）对称性的超对称模型，这在我们之前的工作中特别提出[1]。在这个模型中，为了实现标准模型 (SM) 费米子质量和 Cabibbo-Kobayashi-Maskawa 矩阵，有四个希格斯双峰。沉重的希格斯双峰不可避免地与 SM 费米子具有改变风味的耦合，并在树级别诱导改变风味的中性电流。我们研究了比以前的工作更广泛的参数空间，包括对 LR 破坏尺度\( \mathcal{O} \) (10 ¹³ ) GeV 和超对称破坏尺度\( \mathcal {O} \) (100) TeV。CP 违反了K 中的可观察性–\( \overline{K} \)混合，ϵ _K，强烈约束模型，因此重希格斯质量应该比\( \mathcal{O} \) (100) TeV 重。我们研究了将重希格斯质量设置为 170 TeV 的轻子风味违反 (LFV) 过程。μ → 3 e的分支比和μ - e转换可以大于 10 ^{- 16}，这可以被未来的实验覆盖。我们还研究了预测可测试 LFV 过程的参数区域的微调程度。
