Abstract
Heavy-ion collisions create a hot and dense matter called Quark-Gluon Plasma (QGP). Azimuthal anisotropy of produced particles is sensitive to the transport properties of QGP (the equation of state, speed of sound and specific shear viscosity) and may provide information about initial state of the collision. In this work, we report results for elliptic (\({{\upsilon }_{2}}\)) and triangular (\({{\upsilon }_{3}}\)) flow of charged and identified hadrons (\({{\pi }^{ \pm }},{{K}^{ \pm }},p,\bar {p}\)) in Au + Au collisions at \(\sqrt {{{s}_{{NN}}}} \) = 11.5, 14.5, 19.6, 27, 39, and 62.4 GeV from the STAR experiment at RHIC. Measurements of the collective flow coefficients \({{\upsilon }_{2}}\) and \({{\upsilon }_{3}}\) are presented as a function of particle transverse momentum (\({{p}_{{\text{T}}}}\)) and collision centrality. In addition the number of constituent quark scaling will be presented for these energies.
