Tetraquark Masses by using extension of Gursey-Radicati Mass Formula

Tetraquark states are classified using the $SU(6{)}_{sf}$ spin-flavor symmetry and Young tableau technique. Further, by using the extension of Gursey-Radicati mass formula, masses of tetraquark states are predicted upto good level of accuracy. Also, Decay channels and decay widths of tetraquark states are calculated and found to be in good agreement with the experimental and available theoretical data.
