论文摘要
我们显示了isospin-Rot的$ e^+e^ - \toηπ^-π^+$横截面 - 通过各种协作来衡量 - 与belle $τ^ - \toηπ^-π^0ν_τ$ spectrum,这不能由重大的新型非标准互动来解释。我们首次提供研究这些框架超出三膜tau衰减的标准模型贡献所需的框架。
We show the discrepancy between the isospin-rotated $e^+e^-\toηπ^-π^+$ cross-section -- measured by various collaborations -- and the Belle $τ^-\toηπ^-π^0ν_τ$ spectrum, which cannot be explained by heavy new physics non-standard interactions. We give for the first time the framework needed to study these beyond the standard model contributions in three-meson tau decays.
