Abstract:
If Jaffe and Wilczek's diquark picture for Θ5+ pentaquark is correct, there should also exist a SUF(3) pentaquark octet and singlet with no orbital excitation between the diquark pair, hence JP=12-.These states are lighter than the Θ5+ anti-decuplet ...

The three dimensional Total Routhian Surface calculations are carried out to analyze the four rotational bands in 168Lu observed recently. One of these four bands is identified as tri-axial super-deformed band, which is consistent with the experiment...
