We report our recent study of spin-orbit force between two nucleons in the parity-odd sector from lattice QCD. To examine the quark mass dependence of spin-orbit force, we construct it from Nambu-Bethe-Salpeter wave functions in $^3P_0$,…

In this chapter, the current status on baryon-baryon interactions such as nuclear forces in lattice Quantum ChromoDynamics (QCD) is reviewed. In studies of baryon-baryon interactions in lattice QCD, the most reliable method so far is the…

The energies of the excited states of the Nucleon, $\Delta$ and $\Omega$ are computed in lattice QCD, using two light quarks and one strange quark on anisotropic lattices. The calculation is performed at three values of the light quark…
