Abstract

We investigate the two loop electroweak corrections to B meson rare decays

and

in the minimal supersymmetry standard model (MSSM) extension with two triplets and one singlet (TNMSSM). The new particle contents and interactions in the TNMSSM can affect the theoretical predictions of the branching ratios

and

, and the corrections from two loop diagrams to the process

can reach around

. Considering the latest experimental measurements, the numerical results of

and

in the TNMSSM are presented and analyzed. The findings indicate that the results in the TNMSSM can fit the updated experimental data well, and the new parameters

, clearly affect the theoretical predictions of

and

TNMSSM 中的 B 介子稀有衰变* * 国家自然科学基金资助项目（12075074、12235008、11535002、11705045）、河北省杰出青年学者自然科学基金（A2022201017）、广西自治区自然科学基金（2022GXNSFDA035068）和河北省青年拔尖人才支持计划。

我们研究了B介子稀有衰变的两环电弱修正，以及最小超对称标准模型（MSSM）扩展中的两个三重子和一个单重子（TNMSSM）。TNMSSM中的新粒子内容和相互作用会影响支化比和的理论预测，而两个环图对过程的修正可以达到约......。考虑到最新的实验测量结果，本文介绍并分析了 TNMSSM 中和的数值结果。研究结果表明，TNMSSM 中的结果能够很好地拟合更新的实验数据，而新参数、显然会影响和的理论预测。
