Abstract
We use a group theoretical technique to project out the partition
function for a system of quarks, antiquarks and gluons onto a particular
representation of the internal symmetry group SU(3): the
colour singlet, colour octet and colour 27-plet, at finite temperature.
We do this
to
calculate the thermodynamic quantities for those representations.
We also calculate the change in free energy of the plasma droplet
formed from the hot hadronic gas. We find that the size of the
droplet in the colour-octet representation is smaller than that in
the
colour-singlet representations at different temperatures in the
vicinity of the critical temperatures of the phase transitions.
