我们在来自中微子的超对称标准模型（μνSSM）框架下研究新物理对稀有包容性衰变B→X_s l⁺l⁻的影响。确定并分析了对相关威尔逊系数及其对应粒子的主要贡献。通过对相关参数空间进行系统扫描，阐明了控制这些主要贡献的潜在物理机制，并证明其与实验允许区域的一致性。还纳入了来自衰变B⁻→X_sγ、B_s⁰→μ⁺μ⁻和125 GeV类标准模型希格斯玻色子的实验约束。我们对威尔逊系数对前后不对称性的贡献进行了系统的干涉分解，确定C_7C_10和C_9C_10干涉项是在低q²和高q²区域控制其行为的主要贡献。
英文摘要
We investigate the impact of new physics on the rare inclusive decay $B \to X_{\mathrm{s}} l^{+} l^{-}$ within the framework of the $μ$ from $ν$ Supersymmetric Standard Model ($μν$SSM). The dominant contributions to the relevant Wilson coefficients and their corresponding particles are identified and analyzed. By performing a systematic scan over the relevant parameter space, we elucidate the underlying physical mechanisms governing these dominant contributions and demonstrate their consistency with the experimentally allowed regions. Experimental constraints from the decays $\bar{B} \to X_{\mathrm{s}}γ$, $B_{\mathrm{s}}^{0} \to μ^{+} μ^{-}$, and the $125\,\text{GeV}$ SM-like Higgs boson are also incorporated. We perform a systematic interference decomposition of the Wilson-coefficient contributions to the forward-backward asymmetry, identifying the $C_7C_{10}$ and $C_9C_{10}$ interference terms as the dominant contributions governing its behavior in both the low- and high-$q^2$ regions.
