The nucleon(N)-Omega(Ω) system in the S-wave and spin-2 channel (⁵S₂) is studied from the (2+1)-flavor lattice QCD with nearly physical quark masses (m_π ≃146~MeV and m_K ≃525~MeV). The time-dependent HAL QCD method is employed to convert the lattice QCD data of the two-baryon correlation function to the baryon-baryon potential and eventually to the scattering observables. The NΩ(⁵S₂) potential, obtained under the assumption that its couplings to the D-wave octet-baryon pairs are small, is found to be attractive in all distances and to produce a quasi-bound state near unitarity: In this channel, the scattering length, the effective range and the binding energy from QCD alone read a₀= 5.30(0.44)(^(+0.16)_(-0.01))~fm, r_(eff) = 1.26(0.01)(^(+0.02)_(-0.01))~fm, B = 1.54(0.30)(^(+0.04)_(-0.10))~MeV, respectively. Including the extra Coulomb attraction, the binding energy of pΩ^-(⁵S₂) becomes B_(pΩ^-) = 2.46(0.34)(^(+0.04)_(-0.11))~MeV. Such a spin-2 pΩ^- state could be searched through two-particle correlations in p-p, p-nucleus and nucleus-nucleus collisions.
