论文摘要
获得了带电kaon的半衰减衰变的Dalitz图的表达，包括对O [απ）（Q/M_1）的辐射校正（Q是四摩诺特姆转移，M_1是衰减kaon的质量）的表达。考虑到三体和四体区域的贡献。此外，发出的雄性被认为是极化的，因此分析还集中于评估恒定，横向和正常极化成分的辐射校正。最终公式与准备以数值执行的BREMSSTRAHLUNG光子变量进行三重整合，足以在模型无关的实验分析中使用，是否对真实的光子进行了区分。凭借该过程的弱形构成和斜率参数的数值，发现对MUON极化成分的辐射校正与各自未校正的值相比非常小。
An expression for the Dalitz plot of the semileptonic decay of a charged kaon, including radiative corrections to order O[απ)(q/M_1)], where q is the four-momentum transfer and M_1 is the mass of the decaying kaon, is obtained. Contributions of both the three- and four-body regions are accounted for. Besides, the emitted muon is considered to be polarized so the analysis is also focused on evaluating the radiative corrections to the longitudinal, transverse, and normal polarization components of the muon. The final formulas, with the triple integration of the bremsstrahlung photon variables ready to be performed numerically, are general enough to be used in model-independent experimental analyses whether or not the real photon is discriminated. With the numerical values of the weak form factors and slope parameters of the process, the radiative corrections to the components of the muon polarization are found to be very small compared to their respective uncorrected values.
