FIG. 3: The location of QCD critical point in QCD phase diagram. P$_{1}$ is the phase boundary in bag model (BM), P$_{2}$ is the phase boundary in QPM I and P$_{3}$ is the phase boundary in QPM II. F$_{1}$ is the chemical freezeout line obtained using our HG model. C$_{1}$ ( T$_{c}$ = 183 MeV,µ$_{c}$ = 166 MeV ) is the CEP on P$_{2}$ obtained in QPM I and C$_{2}$ ( T$_{c}$ = 166 MeV,µ$_{c}$ = 155 MeV ) is the CEP on P$_{3}$ obtained in QPM II. The labels used in the figure are explained in the table I. are usually located at µ$_{B}$ < 200 MeV whereas chiral CEP have much larger µ$_{B}$ . So there is a good chance for observing CEP at RHIC by using energy scan [47]. We also find that CEP obtained in our models almost overlaps with the points on the freezeout curve. The freezeout point occurs close to RHIC energy and hence the fluctuations in multiplicity etc. can experimentally provide a clear signal for CEP. Before we conclude we would like to discuss the recent lattice data obtained by de For- crand and Philipsen [12, 13] who used 2+1 and 3 flavors staggered fermions and a taylor expansion in µ$_{q}$/T to study the curvature of the critical surface at very light quark masses
