Description
Momentum correlation functions measured in heavy-ion scattering
experiments have attracted significant attention as a source of
information on the interaction between hyperons and nucleons.
The correlation functions between hyperons and deuteron have been
analyzed using theoretical expressions that approximate the deuteron
as a single particle.However, it is essential to treat the three-body
dynamics, including the relative degrees of freedom of the deuteron,
to obtain more accurate results. To this end, the three-body system
of the hyperon and deuteron is described by the Faddeev equation,
a wave function is constructed using its solution, and a correlation
function that incorporates the three-body dynamics is evaluated.
The effect of the deuteron breakup on the correlation function
between the hyperon and deuteron is then discussed.
