Faddeev calculations of low-energy Λ-deuteron scattering and momentum correlation function

Faddeev calculations of low-energy Λ-deuteron elastic scattering are performed up to Ecm=20 MeV across the deuteron threshold. Phase shifts of the s-wave with $J=1/2$ and $J=3/2$ are calculated using strangeness $S=-1$ hyperon-nucleon interactions in chiral effective field theory NLO13 and NLO19 parametrized by the J{\"u}lich-Bonn group. Effective range parameters, such as a scattering length and an effective range, are determined through the calculated phase shifts. Λ-deuteron momentum correlation functions are evaluated using the Λ-deuteron relative wave function constructed from half-off-shell t-matrices. They are compared with those evaluated using an approximate formula.
