Abstract

In recent years tetraquark and pentaquark states have received much attention due to the significant experimental findings. In this work masses of some heavy tetraquarks are estimated by considering the spin-spin interaction, the dipole-dipole interaction, and the meson-meson interaction. It is found that such interactions give significant mass contributions. The Regge trajectory of X(3872) state is also studied and is found to be non-linear. Masses of some tetraquark states are also proposed.
