氘核光生非相干$π^0$的三体计算

A three-body calculation of incoherent $π^0$ photoproduction on a deuteron

A. Fix, H. Arenhövel

摘要:

非相干$π^0$光生的氘核在$Δ(1232)$区域被处理在一个三体散射的方法使用可分离的两体相互作用。结果提出了总和微分截面。结果表明,一阶以上的高阶项在多次散射序列中的作用是微不足道的,它们的加入不能解释理论与实验之间存在的差异。

英文摘要:

Incoherent $π^0$ photoproduction on a deuteron in the $Δ(1232)$ region is treated in a three-body scattering approach using separable two-body interactions. Results are presented for total and differential cross sections. It turns out that the role of higher order terms beyond the first order in the multiple scattering series is insignificant, and their inclusion cannot explain the existing discrepancy between theory and experiment.
