标题： $Λ$-deuteron momentum correlation functions incorporating deuteron breakup contributions in Faddeev formulation

摘要： 氘核碎裂的影响被估算用于$\Lambda$-氘核动量关联函数。 在计算低能$\Lambda$-氘核散射时，Faddeev振幅不仅可以提供弹性散射部分，还可以提供入射通道和重排通道中的碎裂波函数。 计算使用了在手征有效场理论中参数化的核子-核子（NN）和超子-核子（YN）相互作用。 发现入射通道中的碎裂影响基本上可以忽略不计。 而重排通道中的影响不可忽略，但当源半径大于2.5 fm时，影响并不大。 尽管如此，在分析实验数据时了解这些影响的大小仍然是有价值的。 显示英文摘要

摘要： The effects of the deuteron breakup are estimated for the $\Lambda$-deuteron momentum correlation function. Faddeev amplitudes in calculating low-energy $\Lambda$-deuteron scattering can provide not only the elastic scattering part but also breakup wave functions in the incident and the rearrangement channels. Calculations are carried out using nucleon-nucleon (NN) and hyperon-nucleon (YN) interactions parametrized in chiral effective field theory. The effects of the breakup in the incident channel are found to be marginally insignificant. Those of the rearrangement channel are not negligible, but not large when the source radius is larger than 2.5 fm. Nevertheless, it is worthwhile to have the information on the magnitude of these effects in analyzing the experimental data.
