Description
The HAL QCD method has been established as a reliable method to study hadron-hadron interactions. However, in the $\bar{K} N$ potential, which dynamically generates the $\Lambda (1405)$ as the bound state, singular behavior around the origin has been observed. In order to clarify the cause of such behavior in the HAL QCD method, we calculate the R-correlators and local potentials in an effective model of hadron-hadron interactions and compare it with the $\bar{K} N$ potential in the HAL QCD method.
