Abstract
We present recent results from Al(beam)+Au(target) collisions at root s(NN) = 4.9 GeV and Au+Au collisions at root s(NN) = 4.5 GeV from the STAR fixed-target (FXT) program. We report transverse mass spectra of protons, K-s(0) and Lambda, rapidity density distributions of pi(+/-), K-s(0) and Lambda, directed flow of protons, pi(+/-), K-s(0) and Lambda, and elliptic flow of protons and pi(+/-). These are the first measurements of pion directed and elliptic flow in this energy region. Pion and proton elliptic flow show mass ordering. Measurements are compared with published results from AGS and RHIC. These results demonstrate that the STAR detector performs well in the FXT configuration.
