To study the internal structure of the exotic hadron X(3872), considering the coupled-channel potential between quarks and hadrons is necessary because X(3872) is regarded as a mixture state of cc¯ and D0D¯*0. In this work, we construct the hadron-hadron potentials coupled to the quark channel and study the properties of the D0D¯*0 potentials for X(3872). In particular, we compare various local approximations by focusing on the scattering phase shifts.
