φ-> K^+K^-/K_LK_S衰变的结构相关辐射修正

Structure-dependent radiative corrections to phi -> K^+K^-/K_LK_S decays

F. V. Flores-Baez, G. Lopez Castro

摘要:

目前对φ-> K^+K^-/K_LK_S衰变率比值的预测值比相应的实验值高出约5个标准差。到目前为止,占主导地位的来源的同位旋打破这个比例是相空间(52%)和电磁辐射(4.3%,计算内标量QED)的修正。在这里,我们估计的电磁结构的K介子和其他模型相关的贡献到辐射校正的影响。

英文摘要:

Current predictions for the ratio of phi -> K^+K^-/K_LK_S decay rates exceed the corresponding experimental value in about five standard deviations. By far, the dominant sources of isospin breaking to this ratio are the phase-space (52%) and the electromagnetic radiative (4.3%, computed within scalar QED) corrections. Here we estimate the effects of the electromagnetic structure of kaons and other model-dependent contributions into the radiative corrections.
