Description
In this talk, I review recent results on hadron interactions in lattice QCD, mainly those obtained by the HAL QCD method. In particular, I consider two hadron systems including strange, charm and bottom quarks such as $H$ dibaryon, $\Omega\Omega$, $\Omega_{ccc}\Omega_{ccc}$, $N\phi$, $NJ/\psi$, and tetra quark states $T_{cc}$ and $T_{bb}$. I emphasize the importance of the two-pion exchange contributions in $\Omega\Omega$, $\Omega_{ccc}\Omega_{ccc}$, $N\phi$, $NJ/\psi$ and $T_{cc}$ systems. I also report on experimental studies concerning some of these interactions. Finally I briefly discuss an issue of the left hand cut, which may become relevant in particular for $T_{cc}$.
