Effect of deuteron breakup on the deuteron- <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mi mathvariant="normal">?</mml:mi></mml:math> correlation function

The hadron-deuteron correlation function has attracted many interests as a potential method to access the three-hadron interactions. However, weakly-bound nature of deuteron not been considered in preceding studies. In this study, breakup effect on deuteron-$\Xi^-$ ($d$-$\Xi^-$) $C_{d\Xi^-}$ is investigated. $d$-$\Xi^-$ scattering described by nucleon-nucleon-$\Xi$ three-body reaction model. continuum-discretized coupled-channels method, which fully quantum-mechanical and non-perturbative model, adopted. turns out be sensitive strong interaction enhanced 6--8 % for relative momentum below about 70 MeV/$c$. Low-lying neutron-neutron continuum states are responsible enhancement. Within adopted found appreciable but very significant. Except enhancement several percent, studies without can justified.
