Temperature dependence of diquark mass has been investigated in the
framework of the quasi particle diquark model. The effective mass of the
diquark has been suggested to have a temperature dependence which shows a power
law behavior. The variation of the diquark mass with temperature has been
studied. A decrease in effective mass at temperature T < Tc,
where Tcis the critical
temperature has been observed. Some features of the phase transition have been
discussed. The phase transition is found to be of second order. Temperature
variation of baryon masses has also been studied. The results are compared and
discussed with available works.
