Description The first measurement of the rho(0) - vector meson elliptic flow v(2) at mid-rapidity (vertical bar y vertical bar < 0.5) in 40 - 80 % centrality in Au + Au collisions at root S(NN) = 200 GeV from the STAR experiment at RHIC is presented. The study is through the pi(+)/pi(-) hadronic decay channel of rho(0) which has a branching ratio of similar to 100 %. The analysis is being carried out in two different methods. The v(2) results obtained in these methods are consistent. Number of Constituent Quark (NCQ) scaling of v(2) of rho(0) meson with respect to other hadrons at intermediate p(T) is observed. The rho(0) v(2) favors NCQ = 2 scaling, supporting the coalescence being the dominant mechanism of hadronization in the intermediate p(T) region at RHIC.
