The data were collected using the large acceptance STAR detector at $\\sqrt{s_{NN}}$ = 9.2 GeV from a test run of the collider in the year 2008. Midrapidity results on multiplicity density (dN/dy) in rapidity (y), average transverse momentum (<pT>), particle ratios, elliptic flow, and HBT radii are consistent with the corresponding results at similar $\\sqrt{s_{NN}}$ from fixed target experiments. Directed flow measurements are presented for both midrapidity and forward rapidity regions. Furthermore the collision centrality dependence of identified particle dN/dy, <pT>, and particle ratios are discussed. These results also demonstrate the readiness of the STAR detector to undertake the proposed QCD critical point search and the exploration of the QCD phase diagram at RHIC.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t1","@type":"Dataset","description":"Second order event plane resolution measured in the TPC as a function of collision centrality for.","name":"Table for Figure 5"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t2","@type":"Dataset","description":"Efficiency \u00d7 acceptance for reconstructed pions, kaons, and protons in the TPC as a function of p_T at midrapidity.","name":"Table for Figure 7.1"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t3","@type":"Dataset","description":"Percentage of pion background contribution estimated from HIJING+GEANT as a function of p_T at midrapidity.","name":"Table for Figure 7.2"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t4","@type":"Dataset","description":"Transverse momentum spectra for charged pions at midrapidity.","name":"Table for Figure 8.1"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t5","@type":"Dataset","description":"Transverse momentum spectra for protons at midrapidity.","name":"Table for Figure 8.2"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t6","@type":"Dataset","description":"Transverse momentum spectra for antiprotons at midrapidity.","name":"Table for Figure 8.3"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t7","@type":"Dataset","description":"Transverse momentum spectra for kaons at midrapidity.","name":"Table for Figure 9"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t8","@type":"Dataset","description":"dN/dy of pi+ and proton, normalised by N_part/2.","name":"Table for Figure 10.1"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t9","@type":"Dataset","description":"dN/dy of pi+ and proton, normalised by N_part/2.","name":"Table for Figure 10.2"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t10","@type":"Dataset","description":"dN/dy of pi+ and proton, normalised by N_part/2.","name":"Table for Figure 10.3"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t11","@type":"Dataset","description":"dN/dy of K+ and K-, normalised by N_part/2.","name":"Table for Figure 11.1"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t12","@type":"Dataset","description":"dN/dy of K+ and K-, normalised by N_part/2.","name":"Table for Figure 11.2"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t13","@type":"Dataset","description":"dN/dy of K+ and K-, normalised by N_part/2.","name":"Table for Figure 11.3"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t14","@type":"Dataset","description":"Transverse momentum of pi+, K+ and proton.","name":"Table for Figure 12.1"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t15","@type":"Dataset","description":"Transverse momentum of pi+, K+ and proton.","name":"Table for Figure 12.2"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t16","@type":"Dataset","description":"Transverse momentum of pi+, K+ and proton.","name":"Table for Figure 13"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t17","@type":"Dataset","description":"K-/K+, K-/pi-, p/pi+ and K+/pi+ vs. N_part.","name":"Table for Figures 14.1 & 15.1"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t18","@type":"Dataset","description":"K-/K+, K-/pi-, p/pi+ and K+/pi+ vs. N_part.","name":"Table for Figures 14.2 & 15.2"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t19","@type":"Dataset","description":"K-/K+, K-/pi-, p/pi+ and K+/pi+ vs. N_part.","name":"Table for Figures 14.3 & 15.3"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t20","@type":"Dataset","description":"dN/d_eta, normalised by N_part/2, as a function of sqrt(S_NN).","name":"Table for Figure 16"},{"@id":"https://doi.org/10.17182/hepdata.93265.v1/t21","@type":"Dataset","description":"dN/dy, normalised by N_part/2;
