阈下反K介子-氘散射中的核子反冲效应

The nucleon recoil effect in antikaon-deuteron scattering at threshold

V. Baru, E. Epelbaum, A. Rusetsky

摘要:

我们利用EFT研究了核子反冲在反K介子-氘核散射中的作用。特别是,我们表明,领先的校正出现在订单$ξ^{1/2}$(其中$ξ=m_K/M_N$)的静态项完全取消在双散射过程中。我们计算了高阶反冲修正,并研究了展开法的收敛模式。我们发现,反冲修正的双重散射过程是静态贡献的10-15%的顺序。

英文摘要:

We investigate the role of the nucleon recoil for antikaon-deuteron scattering using EFT. In particular, we show that the leading correction to the static term that appears at order $ξ^{1/2}$ (where $ξ=m_K/M_N$) cancels completely in the double scattering process. We calculate the higher order recoil corrections and study the pattern of convergence of the expansion method. We find that the recoil correction to the double scattering process is of order of 10-15% of the static contribution.
