We study the low-energy d-\(^3\text {He}\) and d-\(^3\text {H}\) elastic scattering using the halo effective field theory (EFT) formalism. For this purpose, we initially focus on the phase shift analysis of S- and P-wave scattering using the effective range expansion (ERE). Using the ERE analysis we determine the unknown EFT low-energy coupling constants and present the leading- and next-to-leading-order EFT results for the phase shift in each channel. Also, the differential cross section versus center-of-mass energy and angle are plotted with comparison to the available experimental data. Our results show good consistency with the present data.

晕有效场理论中$$$ 3 \ text {He} $$ 3 He和$$ ^ 3 \ text {H} $$ 3 H对氘核的低能散射

我们使用光晕有效场理论（EFT）形式主义研究了低能d - \（^ 3 \ text {He} \）和d - \（^ 3 \ text {H} \）弹性散射。为此，我们首先关注使用有效范围扩展（ERE）对S和P波散射进行相移分析。使用ERE分析，我们可以确定未知的EFT低能耦合常数，并给出每个通道中相移的前导和后导EFT结果。同样，将微分截面与质心能量和角度的关系与可用的实验数据进行比较。我们的结果表明与当前数据具有良好的一致性。
