We report new STAR measurements of mid-rapidity yields for the $Lambda$, $bar{Lambda}$, $K^{0}_{S}$, $Xi^{-}$, $bar{Xi}^{+}$, $Omega^{-}$, $bar{Omega}^{+}$ particles in Cu+Cu collisions at sNN{200}, and mid-rapidity yields for the $Lambda$, $bar{Lambda}$, $K^{0}_{S}$ particles in Au+Au at sNN{200}. We show that at a given number of participating nucleons, the production of strange hadrons is higher in Cu+Cu collisions than in Au+Au collisions at the same center-of-mass energy. We find that aspects of the enhancement factors for all particles can be described by a parameterization based on the fraction of participants that undergo multiple collisions.
The azimuthal anisotropic flow of identified and unidentified charged particles has been systematically studied in Cu+Au collisions at $sqrt{s_{_{NN}}}$ = 200 GeV for harmonics $n=$ 1-4 in the pseudorapidity range $|eta|<1$. The directed flow in Cu+A
We present a systematic analysis of two-pion interferometry in Au+Au collisions at $sqrt{s_{rm{NN}}}$ = 62.4 GeV and Cu+Cu collisions at $sqrt{s_{rm{NN}}}$ = 62.4 and 200 GeV using the STAR detector at RHIC. The multiplicity and transverse momentum d
We have studied the dependence of azimuthal anisotropy $v_2$ for inclusive and identified charged hadrons in Au$+$Au and Cu$+$Cu collisions on collision energy, species, and centrality. The values of $v_2$ as a function of transverse momentum $p_T$ a
The $jpsi$ $pt$ spectrum and nuclear modification factor ($raa$) are reported for $pt < 5 gevc$ and $|y|<1$ from 0% to 60% central Au+Au and Cu+Cu collisions at $snn = 200 gev$ at STAR. A significant suppression of $pt$-integrated $jpsi$ production
We present the first measurement of charge-dependent directed flow in Cu+Au collisions at $sqrt{s_{_{NN}}}$ = 200 GeV. The results are presented as a function of the particle transverse momentum and pseudorapidity for different centralities. A finite
