论文摘要
Inspired by the astonishing $7σ$ discrepancy between the recent CDF-II measurement and the standard model prediction on the mass of $W$-boson, we investigate the $λ'$-corrections to the vertex of $μ\toν_μe\bar{ν_e}$ decay in the context of the $R$-parity violating minimal supersymmetric standard model.这些更正可以独立提高$ w $ boson质量。结合最近的$ z $ pole和kaon衰减测量值,可以达到$ m_w \ lyssim 80.37 $ gev。我们发现这些顶点校正无法完全解释CDF结果,即$2σ$,甚至$3σ$级别。但是,这些校正以及倾斜的贡献可以符合CDF-II结果和相关的界限,以$3σ$级别。
Inspired by the astonishing $7σ$ discrepancy between the recent CDF-II measurement and the standard model prediction on the mass of $W$-boson, we investigate the $λ'$-corrections to the vertex of $μ\toν_μe\bar{ν_e}$ decay in the context of the $R$-parity violating minimal supersymmetric standard model. These corrections can raise the $W$-boson mass independently. Combined with recent $Z$-pole and kaon decay measurements, $m_W \lesssim 80.37$ GeV can be reached. We find that these vertex corrections cannot explain the CDF result entirely at the $2σ$ and even $3σ$ levels. However, these corrections together with the oblique contributions can be accordant with the CDF-II result and relevant bounds at the $3σ$ level.
