Popis:	The space-time evolution of the hot and dense fireball of quarks and gluons produced in ultra-relativistic heavy-ion collisions at non-zero baryonic chemical potential and temperature has been studied by using relativistic viscous causal hydrodynamics. For this purpose a numerical code has been developed to solve the relativistic viscous causal hydrodynamics in (3+1)-dimensions with the inclusion of QCD critical point (CP) through the equation of state and scaling behaviour of the transport coefficients. We have evaluated the transverse momentum spectra, directed and elliptic flow coefficients of pions and protons to comprehend the effect of CP on these observables by using this code. It is found that the integration over the entire space-time history of the fireball largely obliterates the effects of CP on the spectra and flow coefficients. Comment: 14 pages, 13 figures
