In QPM I we have shown the results by dashed curve at µ$_{B}$ /T=0.0 and by a dotted curve at µ$_{B}$ /T=2.0. Similarly in QPM II, the solid line represents results at µ$_{B}$ /T=0.0 and the dashed-dotted curve at µ$_{B}$ /T=2.0, respectively. Square and triangular points are lattice data at µ$_{B}$ /T=0.0 and at µ$_{B}$ /T=2.0, respec- tively [28,29]. beyond the critical point where HG pressure which is solely dominated by mesonic pressure term in Eq.(25), is always less than the QGP pressure. Therefore, no phase transition exists in this region. Since the temperature is much higher, the thermal fluctuations break mesonic constituents of HG into quarks, antiquarks and gluons. We have tabulated in Table I the location of CEP obtained from various calculations for a comparison. For convenience we have shown above the dark solid line, all the values obtained in SU(3) flavour calculations. Below the solid line, the values of SU(2) are also shown in order to make the comparison complete. We find that there exists a very wide variation in the coordinates of CEP obtained in different models. We notice that critical end points obtained in deconfining phase transition
