In the framework of the quasiparticle approach, the ground state mass of heavy pentaquarks have been investigated in diquark diquark antiquark picture and the higher states are investigated in the mass loaded flux tube model where two light diquarks are supposed to be linked by a flux tube to the heavy quark. The Regge trajectories for heavy pentaquarks have been studied. The Regge slope (alpha) of these particles have been obtained as approximate to 1 GeV2 which indicates that the Regge trajectory follows the linearity conditions with universal value of alpha (similar to 1 GeV2). The ground state mass of doubly charm and doubly bottom baryons like Xi(++)(cc), Xi(0)(bb), Omega(+)(cc), Omega(-)(bb) have also been investigated in quasiparticle approach. The results are found to be in reasonably good agreement with the experimental and other theoretical estimates.
