The lattice QCD simulation of NJ/psi and N eta(c) scattering is performed at m(n) similar or equal to 266 MeV in channels with all possible J(P). This includes J(P) = 3/2(+/-) and 5/2(+/-) where LHCb discovered P-c (4380) and P-c (4450) pentaquark states in proton-J/psi decay. This is the first lattice simulation that reaches the energies 4.3-4.5 GeV where pentaquarks reside. Several decay ...
