标题： Do heavy sfermions decouple from low energy Standard Model?

摘要： 我们通过分析探讨了在sparticles比电弱尺度重得多的解耦极限中，标准模型如何作为最小超对称标准模型(MSSM)的量子低能有效理论出现。 在本工作中，我们将sfermions积分到一环，并计算它们对标准电弱规范玻色子有效作用量的贡献。 通过分析渐近极限$m_{\tilde f} \gg m_z$中得到的有效作用量，证明了sfermions的解耦。 包括了关于解耦如何通过sparticle的物理质量和非物理的MSSM参数进行的讨论。 显示英文摘要

摘要： We explore analytically how does the Standard Model emerge as the quantum low energy effective theory of the Minimal Supersymmetric Standard Model (MSSM) in the decoupling limit where the sparticles are much heavier than the electroweak scale. In this work we integrate the sfermions to one-loop and compute their contributions to the effective action for standard electroweak gauge bosons. A proof of decoupling of sfermions is performed by analyzing the resulting effective action in the asymptotic limit $m_{\tilde f} \gg m_z$. A discussion on how the decoupling takes place in terms of both the sparticle physical masses and the non-physical MSSM parameters is included.
