Description
Elucidating the nature of exotic hadrons is one of the central challenges in hadron physics. In recent years, numerical simulations based on lattice QCD have become a powerful tool for investigating these hadrons from first principles. The HAL QCD method, which explores hadron interactions in lattice QCD through interaction potentials, has demonstrated particular advantages for systems including baryons.
In this talk, I will present our recent studies using the HAL QCD method on kaon-nucleon and antikaon-nucleon interactions, which are closely related to the $\Theta^+$ pentaquark and the $\Lambda(1405)$ excited baryon, respectively.
