Yields and elliptic flow of d(dbar) and He3(He3bar) in Au+Au collisions at sqrt(sNN)= 200 GeV

Abstract

We present the transverse momentum spectra at mid-rapidity for $d$, $\bar{d}$ ($1<p_T<4GeV/c$) and ${}^{3}He$, $\overline{{}^{3}He}$ ($2<p_T<6GeV/c$) measured by the STAR experiment at RHIC and extract the coalescence parameters $B_2$ and $B_3$ (respectively). We also present the $v_2$ measurement for $d(\bar{d})$ and ${}^{3}He(\overline{{}^{3}He})$. We find that the $d(\bar{d})$ and $p(\bar{p})$ $v_2$ follows the atomic mass number A scaling within errors and a negative $v_2$ has been observed for $\bar{d}$ at low $p_T$.
