Multiquark states as di-hadronic molecules Original Research Article

Multiquark systems such as tetraquarks, pentaquarks and hexaquarks states are studied as di-hadronic molecules in a nonrelativistic model. The masses of several di-hadronic states using a molecular interaction provided by asymptotic expression of the confined gluon exchange potential are computed. The exotic states such as f0 (0.982), f2 (1.565), f2 (1.950), X(3.87), DsJ (2.317, 2.460, 2.632), ψ(4.040) etc are identified as the low lying di-mesonic states, and Θ+ (1.54) as a K−N molecular state.
