Description

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 f$_0$ (0.982), f$_2$ (1.565), f$_2$ (1.950), X(3.87), D$_{sJ}$ (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.
